Nuclear Medicine

Nuclear medicine is a division of radiology that images body functions (as opposed to body structures). It uses only a small dose of radiation and is an attractive, non-invasive alternative to exploratory surgery.

First, a radioactive material (called a tracer) is given orally or by intravenous injection. Once inside the body, the tracer collects in certain areas and reacts with body tissue to produce gamma radiation. All types of nuclear medicine scanning apparatus measure this radiation.

After the tracer is absorbed, the patient lies down on the scanning table and is placed beneath or inside the scanning device (depending on the unit). Cameras detect the emitted gamma radiation, and a computer processes and displays high-quality images.


Nuclear Cardiology

Studying tissue function with nuclear medicine aids in the diagnosis of many kinds of diseases, tumors, infection and other disorders in the brain, heart, lungs, bone, bowel, kidneys, thyroids and other internal structures. Nuclear cardiology focuses on imaging the heart to locate or diagnose problems with the heart. Scans may be performed in conjunction with other types of imaging (CT, MRI, X-ray) or with stress tests to determine the cause of unexplained chest pain.
