What is Nuclear Medicine?

Nuclear Medicine is the use of radioactive material to conduct medical procedures. The most common form of this involves injecting, ingesting, or inhaling radiotracers into the body, and tracking their movement.

During a Nuclear Medicine procedure, radiopharmaceuticals are injected into a vein (usually in the same area where bloodwork is performed). The radiopharmaceutical travels through the bloodstream to the target organ, allowing the radiologist to see the function and structure within the body. Radiopharmaceuticals contain radioisotopes, which emit radiation that is picked up by the Nuclear Medicine camera. This is a small amount of radiation that poses little to no risk or side effects.

Nuclear imaging is primarily used to diagnose or treat illnesses. Conditions diagnosed by nuclear medicine imaging include blood disorders, thyroid disease, heart disease, gallbladder disease, lung disorders, kidney disease, bone infections or breaks, and cancer.
