scanning

 [skan´ing]
1. close visual examination of a small area or of different isolated areas.
2. any of several diagnostic radiologic techniques, including computed tomography, magnetic resonance imaging, and positron emission tomography.
3. a manner of utterance characterized by somewhat regularly recurring pauses.
brain scanning see brain scanning.
MUGA scanning (multiple gated acquisition scanning) equilibrium radionuclide angiocardiography.
radioisotope scanning production of a two-dimensional record or image of the gamma rays emitted by a radioactive isotope concentrated in a specific organ or tissue of the body, as brain, kidney, or thyroid gland.
scintillation scanning the process resulting in a scintiscan.
thallium scanning production of a scintillation scan involving the use of thallium 201; see also thallium scan.
total body scanning use of computed tomography to examine a cross section of the entire body. The scanner produces an image of tissue density in a complete cross section of the part of the body being scanned. Total body scanning does not require the injection of a radiopaque substance, nor is there a need for use of a radioactive material to produce a record of the findings. The total body scanner is particularly useful in visualizing organs in the retroperitoneal space, for example, the pancreas, liver, spleen, and ovaries, and the abdominal section of the aorta.

radioisotope scanning

Recording of gamma ray photons from radioisotopes that have been introduced into tissue, usually by chemical bonding with a drug that targets the tissue or organ of interest.

scanning

close visual, electronic or radiographical examination of a small area or of different isolated areas of the body.

radioisotope scanning
production of a two-dimensional record of the gamma rays emitted by a radioactive isotope concentrated in a specific organ or tissue of the body, such as brain, kidney or thyroid gland.
total body scanning
utilization of computed tomography (CT) to examine a cross-section of the entire body. The CT scanner produces an image of tissue density in a complete cross-section of the part of the body being scanned.
For the most part total body scanning does not require the injection of a radiopaque substance, nor is there a need for use of a radioactive material to produce a record of the findings. However, contrast is used in some areas, particularly the skull, as it enhances the image.
The total body scanner is particularly useful in visualizing organs in the retroperitoneal space, for example, the pancreas, liver, spleen and ovaries, the abdominal section of the aorta, and in viewing the spine and skull.
