EncyclopediaSeenuclear medicineradionuclide imaging
nuclear scanning Any 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.
Risks
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.See RNI
