Related to nuclear scanning: cardiac nuclear scanning
a diagnostic technique that uses an injected, ingested, or inhaled radioactive material and a scanning device to determine the size, shape, location, and function of various body parts. Also called radionuclide organ imaging.
nuclear scanningAny diagnostic procedure (e.g., bone scan, liver scan, thyroid scan) that uses a radioisotope (e.g., 99m-Technetium (99mTc) or 123-iodine (123I)) linked to a molecule that selectively concentrates in a particular tissue. After administration, the compound’s distribution in the body is evaluated using a scintillation camera; any region that is larger, brighter or located in different sites is at least suspicious of harbouring a neoplasm.
The amount of radioactivity in the isotopes used in diagnostic medicine are minimal and pose no threat to health; moreover the body flushes out or “turns over” the radioactive ions within hours to days after the study’s completion.
nuclear scanningRadionuclide imaging Imaging Any diagnostic procedure–eg, bone scan, liver scan, thyroid scan–that use a radioisotope–eg, 99m-Technitium–99mTc or 123-iodine–123I, linked to a molecule that selectively concentrates in a particular tissue; after administration, the compound's distribution in the body is evaluated using a scintillation camera; any region that is larger, brighter, or located in different sites than normal is regarded as diagnostic or at least suspicious of having a disease process. See Bone scan, Thyroid scan.
Use of injected radioactive elements to analyze blood flow.
