radionuclide scan

Radiopharmaceutical study Imaging Imaging of internal organs and tissues after injection or ingestion of a small amount of radioactive material which concentrates or localizes to a particular region or tissue, and is detected with a scanner Pulmonology Ventilation-perfusion scan, see there.

In order to determine whether the mass has a glandular origin, the radionuclide scan or the sialogram are usually performed.
Conventional diagnostic approaches such as history taking, physical examination and routine laboratory tests are not always conclusive; therefore adjunctive tests like ultrasonography, FNAC and radionuclide scan are commonly used to improve diagnostic accuracy.
