X-ray examinations using a liquid barium mixture to locate disorders in the esophagus (esophagogram), duodenum, small intestine (small bowel follow through) and colon (barium enema). Taken before or during the examination, barium causes the intestinal tract to stand out in silhouette when viewed through a fluoroscope or seen on an x-ray film. The barium swallow is used to examine the upper gastrointestinal tract and the barium enema is for examination of the lower gastrointestinal tract.
Term
CARDIAC CATHETERIZATION

A unique x-ray technique for viewing blood vessels by taking two images and subtracting one from the other. Images are first taken without contrast and then again after contrast is injected into blood vessels. The first image is then subtracted from the second so that the final image (sharp and precise) shows only contrast-filled blood vessels minus surrounding tissue.
Term
ECHOCARDIOGRAPHY
Definition
Images of the heart are produced by introducing high-frequency sound waves through the chest into the heart. The sound waves are reflected back from the heart and echoes showing heart structure are displayed on a recording machine. It is a highly useful diagnostic tool in the evaluation of diseases of the valves that separates the heart chambers and diseases of the heart muscle.

X-ray recording of the spinal cord. X-rays are taken of the fluid-filled space surrounding the spinal cord after contrast medium is injected into the subarachnoid space (between the membranes surrounding the spinal cord) at the lumbar level of the back. Myelography detects spinal tumors or ruptured, "slipped," disks that lie between the backbones (vertebrae) and press on the spinal cord.
Term
TOMOGRAM
Definition
X-ray recording that shows an organ in depth. Several pictures ("slices") are taken of an organ by moving the x-ray tube and film in sequence to blur out certain regions and bring others into sharper focus. Tomograms of the kidney and lung are examples.
Term
ULTRASONOGRAM
Definition
Images are produced by beaming sound waves into the body and capturing the echoes that bounce off organs. These echoes are then processed to produce an image, not in the sharpest detail, but showing the difference between fluid and solid masses and the general position of organs.
Term
UPPER GASTROINTESTINAL EXAMINATION
Definition
A liquid contrast substance called barium sulfate is swallowed and x-ray pictures are taken of the esophagus (barium meal or barium swallow), duodenum and small intestine. In a small bowel follow-through, pictures are taken at increasing time intervals to follow the progress of barium through the small intestine. Identification of obstructions or ulcers is possible.
Term

Definition
A radioactive substance is injected intravenously and its uptake in bones is detected by a scanning device. Tumors in bone can be detected by increased uptake of the radioactive material in the area of the lesion.
Term
BRAIN SCAN
Definition
A radioactive substance is injected intravenously and collects in any lesion that disturbs the natural barrier that exists between blood vessels and normal brain tissue (blood-brain barrier), allowing the radioactive substance to enter the brain tissue. A scanning device detects the presence of the radioactive substance and thus can identify an area of tumor, abscess, or hematoma.
Term

Definition
Radioactive substances that release radioactive particles called positrons are injected into the body and travel to areas of the brain.. Because of the way that the positrons are released, cross-sectional color pictures can be made showing the location of the radioactive substance. This test is used to study disorders of the brain and to diagnose strokes, epilepsy, schizophrenia and migraine headaches. Also known as a PET scan.
Term
PULMONARY PERFUSION SCAN
Definition
Radioactive particles are injected intravenously and travel rapidly to areas of the lung that are adequately filled with blood. Regions of obstructed blood flow due to tumor, blood clot, swelling and inflammation can be seen as nonradioactive areas on the scan.
Term
PULMONARY VENTILATION SCAN
Definition
Radioactive gas (xenon-133) is inhaled, and a special camera detects its presence in the lungs. The scan is used to detect lung segments that fail to fill with the radioactive gas. Lack of filling is usually due to diseases that obstruct the bronchial tubes and air sacs. This scan is also used in the evaluation of lung function prior to surgery.
Term
MYOCARDIAL SCAN
Definition
A radioactive substance (thallium chloride-201) is injected intravenously and travels to the heart muscle while the patient is at rest or exercising. Imaging shows up areas that have inadequate collection of radioactive substance, such as areas of blocked blood vessels Also called a thallium scan..
Term
THYROID SCAN
Definition
A radioactive iodine chemical is injected intravenously and collects in the thyroid gland. A scanning device detects the radioactive substance in the gland, measuring it and producing an image of the gland. The increased or decreased activity of the gland is demonstrated by the gland's capacity to use the radioactive iodine. A thyroid scan is used to evaluate the position, size and functioning of the thyroid gland.
