It was not so long ago when people blamed life experiences as the root cause of OCD. However, with the recent advancements of science and with the new discoveries of potent drugs, this old belief has slowly faded out of the scene. The neurobiological basis associated with OCD has been further fortified by the fact that OCD patients do respond to medications specifically formulated to affect the neurotransmitter serotonin. Such findings have led to the dismissal of the notion that OCD can only be attributed to certain behaviors or traits learned in childhood. OCD behaviors such as unusual emphasis to order and cleanliness, or strong rejections to certain societal ideals deemed as dangerous to oneself...

Hepatomegaly (an enlarged liver) indicates potentially reversible primary or secondary liver disease. This sign may stem from diverse pathophysiologic mechanisms, including dilated hepatic sinusoids (in heart failure), persistently high venous pressure leading to liver congestion (in chronic constrictive pericarditis), dysfunction and engorgement of hepatocytes (in hepatitis), fatty infiltration of parenchymal cells causing fibrous tissue (in cirrhosis), distention of liver cells with glycogen (in diabetes), and infiltration of amyloid (in amyloidosis). The lower edge of the liver normally comes just to the lower edge of the ribs (costal margin) on the right side. In its normal state, the edge of...

The experience of optimal functioning called flow enhances creativity, and can be nurtured in our own lives, says the psychologist who developed the concept. Author of "Flow: the Psychology of Optimal Experience" and a number of related books, Mihaly Csikszentmihalyi (pronounced me-high chick-sent-me-high) says we can facilitate the conditions for this experience, and that it may be found in a wide range of careers and activities. For his doctoral thesis on "how visual artists create art" he studied photos taken every three minutes as artists created a painting. He said in a newspaper interview that he was "struck by how deeply they were involved in work, forgetting everything else." He went on to...

Yes, there are ways how to stop ringing ears. It is estimated that ringing ears (tinnitus) affects approximately twenty percent of the American population. While it doesn't bother some, others find they can no longer lead normal lives with this affliction. Research into tinnitus has finally produced many very beneficial therapies. It seems barbaric now, but in the recent past one of the ways to treat tinnitus was to severe the nerves that enable us to hear. This of course was a treatment that was worse than the disease, but it was undertaken by desperate people. Advanced imaging devices like the PET scan (Positron Emission Tomography) and other sophisticated instruments have enabled researchers to...

The most critical form of mesothelioma is the malignant form. Known as malignant mesothelioma, the primary causal factor is asbestos infection. According to the US National Cancer Institute, "Malignant mesothelioma is a disease in which cancer (malignant) cells are found in the sac lining the chest (the pleura), the lining of the abdominal cavity (the peritoneum) or the lining around the heart (the pericardium)." Mesothelioma can be classified into three types - pleural mesothelioma, peritoneal mesothelioma and pericardial mesothelioma. Pleural mesothelioma refers to a cancer of the lining of the lung (pleura), peritoneal mesothelioma refers to a cancer of the abdominal cavity (peritoneum) lining...

MRI, or magnetic resonance imaging, is a common procedure that can find abnormalities throughout the body. It is different from a CT scan because it uses the magnetic force to create signals and reactions with protons in the body. This creates an image of the internal structures that doctors can use to diagnose and treat a variety of conditions. CT scans, on the other hand, are simply complete three dimensional x rays of the body. The cost of MRI scans ranges between $600 and $3500, depending on where your procedure is done and how intensive it is. For example, having an MRI of your head or chest would be much less expensive than having an MRI of your whole body done. The more time it takes and the...

Magnetic resonance imaging is an accurate imaging system that greatly helps in evaluating lumbar spine disorders. MRI for lumbar spine is carried out by making use of magnetic fields and radio waves along with a computer to develop images of the spine. This diagnostic procedure is capable of developing three dimensional images with excellent clarity. MRI for a Better Evaluation of Bodily Abnormalities The reason behind many doctors preferring MRI for their patients is its accuracy. It can provide a clearer, more detailed picture of the disorders in the body structure, which cannot be identified through X-rays, ultrasound and CT scans. MRI for lumbar spine can precisely diagnose the disorders in the...

MRI (Magnetic resonance imaging) is a non-invasive imaging technique that uses a combination of a large magnet, radio frequencies, and a computer to generate images of internal structures and organs of the body without using x-ray radiation and surgery. MRI has been developed based on the principles of nuclear magnetic resonance. NMR (nuclear magnetic resonance) was discovered by Felix Bloch and Edward Purcell in 1946. During the 1950s and 1960s, NMR (nuclear magnetic resonance) was used for chemical and physical molecular analysis. In 1971, Raymond Damadian showed that the nuclear magnetic relaxation periods of tissues and tumors differed. In 1973, Paul Lauterbur used a back projection technique...

1. Diagnosis Diagnosis is a strength of Western scientific medicine because of its dependence on analytical procedures and processes of elimination. Modern technology has given us many ways to see into the body for effective diagnosis of dis-ease. Nowhere is scientific Western medicine so advanced than in the fields of diagnosis. Although the philosophy of Western medicine often comes in for criticism, modern science has produced many ways in which we can examine and image organisms internally and take samples of tissue in hard to reach places. A qualified doctor should always be the first point of contact for serious disease as they have a good chance of getting you a correct diagnosis. Self...

The Magic School Bus is great in theory. But climbing aboard a big yellow school bus, shrinking down the cellular scale and invading the body and its systems has yet to be accomplished by science. Some of you might feel disappointment when it comes to the lack of the minuscule vehicle, but the goal of exploring the human body may still be possible. X-rays and scans have been used to gauge extent of trauma, locate malfunctioning organs and diseased tissue. But recent developments and creative techniques have been recently introduced into the medical world. Medical technology is now able to give a clearer and more valuable picture of tissue, blood and bone than ever before. For years, X-rays have been...

Since the beginning of hypnosis, there has been an ongoing debate as to the reality of he process. There are as many individuals who believe that hypnosis is a real state of consciousness as there are individuals who do not believe hypnosis is real. In an effort to prove whether or not a state of hypnosis can be induced, the scientific community has performed its own studies and garnered significant information. Scientists have subjected individuals to a host of examinations to determine if there are any physiological changes that take place in the body during hypnosis. The results have been interesting and enlightening. After hooking people up to a multitude of machines, scientists have discovered...

-> It has always been fascinating to hear that you should get a second opinion. There are times when it may be even to your advantage to get more than a second, after all, they are opinions. Doctors are given access to a variety of tools at their disposal to help them form their opinion. Different hospitals in Illinois have different tools which they can offer to doctors that include MRI, CAT scan, x-ray, PET scan, biopsy tools and a variety of different labs in which to process tests like urine and blood tests. Different doctors are trained to use different tools and they then confer with other doctors to come to an opinion. There are doctors who interpret x-rays, CAT scan, PET scans and MRIs. Each...

Now there are methods to stop ringing ears. These methods are proving highly beneficial and are producing best results. While, Tinnitus as it is rightly called doesn't cause inconveniences to some people but there are others who feel that they can no longer go ahead and lead normal lives with this misery. Investigation into tinnitus has ultimately produced many valuable therapies. Highly developed devices like the PET scan-Positron Emission Tomography and other complicated tools have enabled the researchers to look for efficient cure for tinnitus. One technique is called Tinnitus Retraining Therapy or TRT which has been confirmed to work. TRT healing consists of relaxation therapy and psychosomatic...

A person working with asbestos is the highest risk. It's been said that about 75% of all cases have histories exposure to asbestos at work. There are about 2,000 to 3,000 mesothelioma cases reported each year and most of them are work-related cases. Asbestos minerals are said to be strongly present on industrial materials and products such as flooring products, roof shingles, insulations, textiles, cement and brake linings. Some of these materials are also used in industries such as construction, automotive, shipyard and manufacturing. A worker can get it just by inhaling and swallowing the substance. Moreover, there are theories that members of the family of these workers are prone to second hand...

Having CT scans, MRIs and other tests done to diagnose and treat diseases and conditions is common practice in the medical world. In most cases, these tests are covered by the medical insurance or Medicare of the patient, if they have either. More recently, doctors are discovering the use of these tests to aid in prevention and healthy living. However, insurance companies will not usually cover these tests, so few people are able to actually get them. A preventative scan can be done on a regular basis, such as yearly, to help make sure that you are in good health and not susceptible to various diseases and conditions. These scans can be done on any part of the body. You can have a heart scan, a full...

Although a good part of the state includes communities that serve as the home bases for men and women who spend their workdays in the nation's capital, Maryland is much more than an appendage of the District of Columbia. Indeed, oftentimes overlooked in the 1970s and 1980s, beginning in the 1990s and moving onward into the 21st century, Maryland really has become a destination of distinction for people from all walks of life looking to find homes in a state that has much to offer. Of course, Maryland is a state with a tremendously rich history. From colonial venues to Civil War sites to other exciting and interesting points of interest, both residents of and visitors to Maryland have a great deal...

Because of the complexity of the brain and the way it interacts with the rest of the body, a traumatic brain injury can result in many different problems, disorders, and/or complications. Diagnosing the extent of a traumatic brain injury is no easy task. Modern technology has provided doctors and scientists with several effective imaging procedures which allow them to study the effects of an injury on the brain and produce more accurate diagnoses of any problems. Two of the most widely used techniques are computerized tomography (CT) scans and magnetic resonance imaging (MRI). Computerized Tomography The term tomography comes from the Greek word tomos, meaning "section." A tomograph, therefore, is a...

A leaking heart valve fortunately, does not always mean valve surgery. And, heart valve surgery, if it becomes necessary, does not always have to mean that you'll need an open-heart surgery. In fact, most people with a leaking valve disorder, are totally unaware of their valvular disease. Their mildly leaking valve condition goes undetected because it just never progresses to the point of needing treatment. Symptoms which might indicate that your leaking heart valve also called valve regurgitation is worsening to the point of needing some form of treatment are: unexplained fatigue, shortness-of-breath especially when you exert yourself, heart palpitations, an awareness of your heart beat, fluttery...

The sudden onset of a deadly cancer is possibly the last thing on your mind when you feel "not so normal". However victims of asbestos cancer (mesothelioma) barely survive 12 months, after being diagnosed with this cancer. The two most common forms of mesothelioma have different symptoms, relating to different parts of the body. Pleural mesothilioma (present in the lining surrounding the lungs) and peritoneal mesothilioma (present in the lining surrounding the abdominal cavity and the abdominal organs) may display signs of other unrelated illnesses, however the immediate affects can be quite deadly. For instance, peritoneal mesothilioma, the rarer of the two, can lead to swelling, abdominal pain due...

Headaches can be very distressing. They are a common symptom and many headaches are self-limiting and do not represent anything too serious. There are different types of headache. The main classification is in to primary and secondary. A secondary headache is caused by something else and the resulting headache is not a clinical condition in itself. Examples include things such as sinus problems, allergic disease, tooth or mouth disorders, a blow to the head or cancer of the brain or other swellings or pressure effects A fact about headaches Women are typically afflicted with tension headaches more often than men Some headache information Chronic muscle-contraction headaches can last for weeks...

Health insurance is a highly necessary financial scheme that one should have, especially at present when the medical bills and hospital expenses are on the rise like never before. These days, even a normal hospital check up can cost you a large amount of money. There are various kinds of tests like MRI scan and CT scan that are not so inexpensive and there are modern medicines that are always high priced. In such a scenario, availing a health insurance for the whole family is a wise decision. But a study recently revealed that there are about 50 million people in United States who do not have any kind of health insurance policy for themselves or their family. The main reason for them not taking a...

What are the types of reports that need to be transcribed? A patient-provider interaction typically happens when a patient visits a doctor or healthcare provider for: - Regular health checks - Specific health issue - Emergency care - Specialist referral - Procedure - Surgery/ Diagnostic test Once the patient-doctor encounter ends detailed records need to be created of the whole process. This is not only a statutory requirement, but also aids the doctor in the treatment process, checking on the progress of the patient, providing proof in case of litigation and also used further for billing and reimbursement. Medical transcription plays an important part in the process of record creation. The types of...

It is very difficult to identify as to which kind of headache a person is suffering from. The five kinds of headaches are sinus headache, tension headache, rebound tension, migraine headache or cluster headache. If one could identify what kind of headache he or she is going through then the right treatment could be prescribed. In one of the study of 2004, eighty percent of the patients with the current history regarding doctor diagnosed or self described sinus headache were noted, however not even one signs of the sinus infection was seen, generally it matched to criteria for the migraine. And about 2/3rd of these victims expressed their dissatisfaction regarding the medications which were...

What causes whiplash? Whiplash occurs when the soft tissue in the spine is stretched and strained after the body is thrown in a sudden, forceful jerk. The injury most commonly occurs in car crashes involving sudden deceleration, but the injury can also occur in other strenuous physical activities such as diving. What does whiplash feel like? The most frequent complaints are headaches and stiffness in the neck and the back of the head. These symptoms appear within the first couple of days after the accident and usually pass after a few days to a few weeks. Is whiplash dangerous? A doctor or hospital should be alerted if the patient experiences memory loss or periods of unconsciousness after a...

"Meningitis" and "encephalitis" are two words that pop onto most people's radar screens from time to time, and usually in some scary context, like hearing of a cluster of cases in their child's school, or reading media reports of epidemics occurring nationally or internationally. While most people understand that these words mean there is some sort of infection of the nervous system, other distinctions and implications are often left unstated and, as a result, can be vague or confusing. The basic concepts are built into the words themselves. Starting at the ends of the words and working forwards, "-itis" is the medical suffix meaning inflammation. Although it's possible for inflammation to occur...

One advice that a doctor will give you when you receive a pacemaker is to be careful of certain electrical appliances and devices, especially those that emit charges. But can outside electrical source interfere with your pacemaker? Unfortunately yes and these electrical sources can be detrimental and sometimes fatal. MRI, also known as magnetic resonance imaging, is a type of scan that is used to study images of the brain, liver, spine, joints and other organs. This machine gives out a strong magnetic field which interferes with the proper functioning of a pacemaker. Therefore, patients with pacemakers should not have an MRI scan. Doctors will also warn you about mobile phones. Make sure you do not...

What Is Tinnitus? Tinnitus is marked by ringing or buzzing noises in the ear without any clear reason for it, and can indicate a more serious underlying condition, such as tumors or an infection. Tinnitus can be constant, intermittent, or pulsating. It is most always a chronic condition, but can be managed successfully to reduce it's irritating effects. Tinnitus can be unilateral (one ear) or bilateral (both ears). The word is derived from the Latin tinnitus, or "ringing." It has been a bone of contention for thousands of years, and treatments have varied throughout the ages. There exists two kinds of tinnitus. In subjective tinnitus, only the person can hear it. In objective tinnitus, your...

The injury known as whiplash causes damage to your ligaments/tendons, which is the tissue that connects your bones; whiplash also causes damage to the muscles in your neck. It is an injury that you are mostly likely to gain in a road traffic accident, when the collision jolts your head forwards. Road traffic accidents may be the most common way that we end up suffering from whiplash but it isn't the only way. You could also end up suffering the results of whiplash due to a blow to the head or as the result of long term repetitive damage. Also if your whiplash injury was caused by a road traffic accident it doesn't matter where your car is hit as whiplash can occur regardless of whether your head is...

If you have ever suffered from a pinched nerve you know how painful it can be. Chances are you experienced numbness or decreased sensation in the area supplied by the nerve or a tingling, "pins and needles" feeling. Some of my patients tell me they feel a sharp or burning pain which is aggravated by coughing or sneezing. Sometimes they may feel twitching in the affected area or like their foot or hand has "fallen asleep." I have to tell you that I sympathize with how my patients are feeling and congratulate them for seeing a doctor. So often people wait too long before seeing a specialist and suffer in silence before treatment relieves their symptoms. You should see your doctor if the signs of a...

Spinal stenosis is a narrowing of the spinal canal resulting in a lack of space to accommodate the nerves. The spinal canal contains the nerves that connect to the skin and muscles of the legs. A normal size canal has sufficient space to hold these nerves. But, as a person ages, the canal is subject to narrowing. The narrowing may not always result in problems. But if the narrowing causes pinching of the spinal nerves, problems will develop. Spinal stenosis isn't always caused by degeneration due to age. It can also be due to tumors, herniated discs, and injuries resulting from accidents. Spinal stenosis can even be present at birth but this is rare. The symptoms of spinal stenosis vary depending...

The principal dilemma in current management of multiple sclerosis is that while early diagnosis enables damage-sparing treatment to begin, diagnosing MS too early increases the likelihood of treating people who don't actually have the disease. Current disease-modifying drugs are all given by injection and cost about $14,000 per year. Apart from being inconvenient and expensive, there is some risk of harm from them which, if the patient doesn't actually have MS, occurs without any offsetting benefit. The dilemma would not be great if multiple sclerosis was easy to diagnose, but unfortunately MS is among the most difficult diagnoses in all of medicine to make, at least while still in its early stages...

Our tonsils are little gland like structures that are present at the rear portion of the throat. The tonsils help catch bacteria and viruses that are present in the mouth and hence prevent them from causing an infection. The mixture of mucous and bacteria that are trapped inside may sometimes concentrate, harden and calcify to form a tonsil stone. A person who has this may experience certain symptoms such as bad breath, a sore throat, and visible lumpy white material present at the back of the throat. Bad breath can sometimes be caused due to the presence of certain chemical compounds such as sulfur compounds. If sulfur compounds are detected in a person's breath there may be a high chance that the...

"> Majority of mesothelioma (cancerous tumor affecting mesothelial cells of organs) cases come under the classification 'pleural mesothelioma'. This is a cancer that originates in the pleura, the delicate membrane covering the lungs. Out of these, seventy five percent are diffuse malignant pleural mesethelioma. The balance is localized or benign. Diffuse malignant pleural mesothelioma is, in most cases, caused by unprotected exposure to asbestos. The symptoms include shortness of breath and/or chest pain, loss of weight, cough, fatigue, swelling on the face, neck and arms, reduced appetite, and coughing up blood. There would be collection of fluid in the thoracic cavity. It may take from twenty to...

There are a variety of details in the advancement of a person's mesothelioma prognosis and fine differences amongst these details may have a dramatic impact on the course the disease will take. The statistical models employed in mesothelioma often miss the extraordinary differences between a person's stated prognosis/diagnosis and the way in which the disease actually impacts his or her life. Stage is important for determining mesothelioma prognosis because it can be for other cancers. However, mesothelioma stats are hard to find, and the stats that exist are unreliable. Early diagnosis and remedy are alot of important in looking for a favorable mesothelioma prognosis. Since mesothelioma is usually...

Respiratory alkalosis treatment is done at affordable cost in India Introduction Background Respiratory alkalosis is a clinical disturbance due to alveolar hyperventilation. Alveolar hyperventilation leads to a decreased partial pressure of arterial carbon dioxide (PaCO2), or partial pressure of carbon dioxide (PCO2). In turn, the decrease in PCO2 increases the ratio of bicarbonate concentration to PCO2 and increases the pH level. The decrease in PCO2 (hypocapnia) develops when a strong respiratory stimulus causes the lungs to remove more carbon dioxide than is produced metabolically in the tissues. Respiratory alkalosis can be acute or chronic. In acute respiratory alkalosis, the PCO2 level is...

Mesothelioma or malignant mesothelioma is a rare form of cancer which is developed from the inhalation or exposure to asbestos particles, dust or fiber. The cancer is developed around the protective lining which covers many of the body's internal organs such as the outer lining of the chest (pleura) or the heart. Some of the symptoms are shortness of breath, chest wall pain and weight loss. Malignant mesothelioma can be detected via CT scan or chest X-ray. It can be confirmed by conducting a biopsy. Malignant mesothelioma is a debilitating disease. It deprives the person from having a normal life and an active occupation. Furthermore, it costs hundreds to thousands of dollars in medical bills. By...

Many people often misunderstood sciatica. Sciatica is the pain in your lower back that travels down your leg. It is a set of symptoms that occur somewhere along the path of the sciatic nerve. It describes the type of pain you might be having, but it doesn't explain why you have it. Dancers are vulnerable to sciatica because of the amount of focus on turning out their legs. This often leads to piriformis syndrome. Dancers also move in a large range of motion at the spine, which result in undue pressure on the spinal discs when alignment or body mechanics is poor. This can lead to herniated discs. Poor body mechanics, arthritis, and scoliosis can be factors in spinal stenosis which leads to sciatic...

  Gallstones are solid lumps or stones that form in the gallbladder or bile duct. They are formed when some of the chemicals stored in the gallbladder harden into a mass. About one in three women and one in five men have gallstones by the age of 75. Some people get just one large stone; others may have lots of tiny ones. What causes gallstones? Scientists believe cholesterol stones form when bile contains too much cholesterol, too much bilirubin, or not enough bile salts, or when the gallbladder does not empty completely or often enough. The reason these imbalances occur is not known. The cause of pigment stones is not fully understood. The stones tend to develop in people who have liver cirrhosis...

While cysts - tiny sacs that contain fluid or liquid that may be semi-solid - can occur anywhere within the body, when the development of cysts occur in the kidneys these are known as "renal cysts". In the majority of cases these cysts cause no harm, are not cancerous, and will go unnoticed causing no symptoms throughout the life of an individual, however, in some cases these can cause complications and some types of cysts may be an indication of the presence of cancer within the kidneys. In the instances where the cysts are causing an issue or it is believed that they have the potential to become cancerous, a physician may recommend that they be surgically removed. The Basic Types of Renal Cysts...

A spinal disc starts to break as it becomes less elastic. And when it does, part of the spinal disc pushes outside the normal boundary - the case is called a herniated disk. When a disc bulges out from between the vertebrae, the nerves of the spine and spinal cord result into being pinched. There is normally some extra room around the spinal cord and it's nerves, but if enough of the herniated disc is pushed out of place, then these parts begin to compress. Imaging techniques for spinal herniated discs is indispensable in diagnosing this problem and in ruling out other symptoms that may lead to identical symptoms, such as disc degeneration, spondylolisthesis, tumors, metastases and other space...

A Radiologic technologist performs all types of imaging procedures, most commonly x-rays. They also administer non-radioactive isotopes known as contrast media for diagnostic purposes. Radiologic technologists are also known as radiographers or x-ray techs. They provide a high standard of patient care, prepare patients for examinations, and explain procedures. Radiologic technologists have a thorough understanding of anatomy, positioning, radiographic exposure, patient care and radiation protection. Radiologic technologists follow physician's orders and conform to the regulations concerning the use of radiation to protect themselves, the patients and co workers. With experience radiographers perform...

If you suspect you are a loved one may have had a stroke, it is essential that you seek immediate medical attention even if the symptoms seem to go away on their own. When a patient is suspected of having a stroke, a physician will run a series of tests in order to make an accurate diagnosis and determine the best form of treatment. The first step in this procedure is to examine the patient's medical history and inquire about the symptoms they are currently experiencing or any past symptoms they may have had. If the patient is unable to communicate, a family member or friend may assist the physician in providing the necessary information. Initial Examination in Diagnosing a Stroke A full medical...

For a healthy and long life threatening diseases like cancer, diabetes and heart diseases have to be prevented or treated effectively. Risk of developing such diseases can be reduced by taking upstream measures ( i.e.) take corrective action well before the disease strikes. Cancer is one such life threatening disease. Even if effectively treated it can severely reduce the quality of life and impose severe costs. Periodic testing for cancer has to be done at least once a year for all those who are above 30 years of age. This may seem too early but alarmingly cancer seems to strike young now. Not only cancer the other so called old man's diseases like diabetes, Alzheimer's disease, Type 2 diabetes...

Mastoiditis is an infection of the spaces within the mastoid bone. It is almost always associated with otitis media, an infection of the middle ear. In the most serious cases, the bone itself becomes infected. It may spread into small cavities in the bone, blocking their drainage. Very severe cases infect the whole middle ear cleft. Mastoiditis is an inflammation or infection of the mastoid bone, which is a portion of the temporal bone. The mastoid consists of air cells that drain the middle ear. Mastoiditis occurs equally in males and females. Mastoiditis most commonly affects children. Mastoiditis develops when middle ear inflammation spreads to the mastoid air cells, resulting in infection and...

Astrocytoma brain cancer tumors are considered to be the most common type of Glioma. These tumors may develop in various regions of the brain, as well as the spinal cord. These particular type of brain cancer tumors initiate from cells that are called astrocytes. The area of the brain that these are most commonly identified is the main region. This is commonly referred to as the cerebrum. It has been established that these have the capability of affecting any individual, at any time in their life. While there have been cases of Astrocytoma a brain cancer tumor in children, this condition is most often diagnosed among those that are part of the adult population. When children are diagnosed with these...

While King Tut has been dead for over 3,300 years, it only took two years for scientists to unlock the mystery of his death. In 1922, Howard Carter struck archeological gold when he discovered the tomb of the renowned King. Now, nearly 90 years later, the body of Pharaoh Tutankhamen is making headline news again. Who exactly was this ruler of ancient Egypt? Ironically, the discovery of the King's body is what ignited the public's interest in him. Experts believe that Tutankhamen was the leader of the 18th Dynasty in Egypt. Since he likely died in his late teens and only ruled for nine years, Tut has earned the moniker of the "Boy King". Some 1968 X-rays caused scientists to conclude that perhaps...

Three out of every four (often high) doses of radiation used for heart scans are clearly inappropriate, according to a review of medical records at the Mayo Clinic. CT scans of the chest or abdomen involve up to ten times the natural radiation from the sun and soil over the course of an entire year, or anywhere from 13 percent up to 40 percent of the minimum radiation received by survivors of the Japanese atomic bomb blasts in 1945, or the Chernobyl nuclear accident in 1986. A study by Columbia University researchers estimates that up to two percent of all Cancers in America in the next few decades could be the result of CT scan radiation exposure now being given to patients. Other studies estimate...

Why Image Fusion Multisensor data fusion has become a discipline to which more and more general formal solutions to a number of application cases are demanded. Several situations in image processing simultaneously require high spatial and high spectral information in a single image. This is important in remote sensing. However, the instruments are not capable of providing such information either by design or because of observational constraints. One possible solution for this is data fusion. Standard Image Fusion Methods Image fusion methods can be broadly classified into two - spatial domain fusion and transform domain fusion. The fusion methods such as averaging, Brovey method, principal component...
