Nuclear medicine imaging non-invasively provides functional information at the molecular and cellular level that contributes to the determination of health status by measuring the uptake and turnover of target-specific radiotracers in tissue. Nuclear medicine imaging is also called radionuclide scanning.
Nuclear medicine imaging is an effective diagnostic tool because it shows not only the anatomy (structure) of an organ or body part, but the function of the organ as well. Nuclear medicine images can be used to find tumours in both tumour concentrates and rest of the organ or tissue concentrates, and to check the structure and function of tissues or organ, detect disease in organs or bones, determine the stage of cancer and to know effect cancer treatment. There are 4 different types of nuclear medicine images called dynamic, planar (static), whole body, single photon emission computed tomography (SPECT). Common types of nuclear medicine imaging are bone scan, gallium scan, MUGA scan, MIBG scan and PET scan.
