Nuclear Medicine

As part of a comprehensive diagnostic plan, your Advanced Imaging physician might refer you for Nuclear Medicine studies.

What is a Nuclear Medicine Scan?
A nuclear medicine (NM) scan is a diagnostic exam that provides your doctor with important information about organ function.

In nuclear medicine, imaging radiopharmaceuticals (radioactive medicine or tracers) are taken orally, by intravenous injection or inhalation. Special cameras then capture and form images from the radiation emitted by the radiopharmaceuticals in the body. This process is different from diagnostic X-rays which pass external radiation through the body to form the images.

NM scans determine the presence of disease based on biological and anatomical changes; i.e. how an organ functions, and what it looks like. Nuclear Medicine scans allow us to evaluate the function of a number of organs including the thyroid gland, lungs, heart, stomach,kidneys, and gallbladder.

Further, NM scans allow us to monitor certain types of cancer, detect a number of bone and joint abnormalities such as fractures, arthritis or tumors, and evaluate certain neurological diseases, infection and blood volume.
