What is a Nuclear Medicine Scan?

Nuclear medicine is a field of medical imaging that uses small amounts of radioactive tracer to diagnose a wide range of disease.

A nuclear medicine scan is used to study the structure and function of an organ, tissue, bone or system of the body. A nuclear medicine scan can detect and monitor many types of cancer. It uses imaging to see how your body absorbs and processes the tracer. We usually inject the tracer into your vein or ask you to swallow it by mouth or breathe it in as a gas depending on your type of scan.

A Note About Tracers

We use the lowest dose of radioactive tracer to get the highest quality images. Radiation exposure during a nuclear medicine scan is minimal. We limit exposure by carefully tailoring the dose to each patient. After the scan, the tracer loses its radioactivity, usually within 24 hours, and passes out of your body naturally.

How to Prepare for a Nuclear Medicine Scan

A nuclear medicine scan can take as little as 2 hours. But some scans require you to leave and come back later in the day or even over several days. You will get more information when your exam is scheduled.
