Lung cancer remains the single largest cause of cancer death in the United States, resulting in over 162,000 deaths in 2006, the National Cancer Institute states. Many lung cancers are not detected until they've already metastasized, or spread to...
A computerized tomagraphy (CT) scan and nuclear bone scan are both radiological procedures used to visualize different parts of the body for disease and disorder detection. A CT scan is a type of X-ray, while a bone scan is more invasive than an...
A computerized tomography, or CT, scan is a diagnostic testing procedure that involves taking X-rays to create cross-sectional images of an area of the body. For many CT scans, a contrast material, or dye, is swallowed or injected to emphasize...
Parkinson's disease is a progressive, neurological disorder that typically strikes people age 60 and above but also can affect people as young as 30. Early diagnosis is important so patients can begin treatment, which can include medications,...
CT, which is the abbreviation for Computed Tomography, is an imaging modality that uses the combination of X-rays and computers to create an image. The images created by CT scan are cross-sectionals of the body part. All of these cross-sectional...
Human imaging is a crucial field in medicine for evaluating and diagnosing a variety of diseases and conditions. One such technique called computed tomography, or CT scan, has become one of the most frequently used imaging techniques since its...
CT scans are a diagnostic procedure, which uses an X-ray beam that rotate around the body. During this rotation, pictures are taken of the body from different views. The computer than converts those various views into a detailed image of the body...
Computed tomography (CT) is a non-invasive procedure that uses x-rays to create images of organs or blood vessels inside the body. The CT scanner machine creates 2-D image "slices" of the body. A computer then combines the 2-D images to create...
Computer axial tomography scans are also called CAT scans and CT scans. Starting in the 1970s, this technology became wildly popular as more and more hospitals sought to expand their imaging capabilities. The CT scan was a revolutionary advance...
A computerized tomography scan---known as a CT or CAT scan---is an upgraded version of an X-ray combined with computer technology. The result is a clearer, more-detailed view of the inside the body. CT scans can produce pictures of an individual's...
A CT or CAT scan is the informal name for computerized tomography, which combines many X-ray images from different angles into a cross-sectional or even 3-D image of the body, according to MayoClinic.com. This computer-enhanced image provides far...
Beginning around 1970, CT scans, or computer axial tomagraphy scans, became a popular imaging tool. They were particularly helpful when imaging areas of the body such as the brain that were otherwise inaccessible. With this new capability,...
Computed tomography (CT) is a non-invasive diagnostic tool in which a source producing x-rays and an x-ray detector are rotated around a person. According to Merck Manuals, an online medical library, CT scanners have 4 to 64, or even more, rows of...
Images obtained by a CT scan generally appear on a monitor as shades of gray. Because these structures resemble each other without contrast, a contrast agent is injected intravenously (in the vein) to highlight the structures that need to be...
CT scans are a radiographic test used to identify heart disease, blood clots, broken bones and cancers quickly and painlessly. Also known as computed tomography, the CT scanner takes pictures in slices, providing a transaxial view of all soft...
In the field of radiology, it is critical to follow all safety precautions and departmental policies. And with pediatric imaging, doctors must be extremely careful with radiation doses, because of the sensitivity of children's rapidly dividing...
A bone scan is a test used to detect arthritis or other degenerative bone diseases, avascular necrosis, bone infections, bone tumors, fibrous dysplasia, fractures, Paget's disease, rickets or metastatic tumors, according to Medline Plus. Your...
Cardiac scans can be performed using computed tomography (CT), a common test that makes use of x-rays to take pictures of the heart. Different types of cardiac CT scans are used to detect varying problems with the heart, including blood clots or...
Today's physicians have a tremendous number of tools at their disposal to help them see what may be going on inside a patient's brain. But the same set of tools that makes them more informed than ever before can make patients more intimidated...
Lung cancer is the leading cause of death among both men and women in the United States, according to the Mayo Clinic. Should you begin displaying symptoms, such as coughing up blood, shortness of breath and a chronic cough, undergo testing as...
Migraines are a form of severe headache with pain that can last anywhere from several hours to several days. Migraines appear to come out of nowhere; however, there is usually an onset warning such as seeing a flash of light, called auras, or...
A diagnosis of epilepsy involves a combination of observation and diagnostic tests. The doctor will listen to a description of the seizures a person has, and perhaps monitor the patient using video for a few hours or days to try and observe a...
The aorta is the main blood vessel coming off of the heart to deliver blood to the rest of the body. It leaves the left side of the heart and travels up into the chest then curves down, enters the abdominal cavity, and continues on until splitting...
Health care providers use heart scan procedures to get detailed views of the condition and functioning of the heart. These procedures help in diagnosis and management of different medical conditions related to the heart, the blood vessels...
CT scans also known as CAT scans or computer axial tomography have many medical and non-medical uses. This enhanced imaging technique came into popular use in the 1970's in hospitals where the three dimensional images were a large improvement...
As the CT scan became more popularly available, people tried to expand its use from a diagnostic tool to a screening tool. The use of CT scans in screening smokers for lung cancer became particularly controversial. Since 85 percent of all lung...
Radiography is a broad term that covers multiple subgroups of medical imaging. All radiography allows doctors to look inside your body at the underlying tissues and organs to determine if there is a problem. All images are reviewed by a...
The American Cancer Society reports that ovarian cancer is one of the most common cancers among women; as many as one out of every 71 women will develop ovarian cancer in her lifetime. Women who have the earliest stages of ovarian cancer do not...
