Nuclear medicine is a specialty that uses safe, painless and cost-effective techniques to take images of the body and treat disease. Nuclear medicine gathers medical information that would otherwise be unavailable, require surgery or may necessitate more expensive diagnostic tests. Nuclear medicine imaging procedures often can identify abnormalities very early in the progress of a disease – long before many medical problems are apparent with other diagnostic tests.

Nuclear medicine uses very small amounts of radioactive materials, called radiopharmaceuticals, to diagnose and to treat disease. In imaging, the radiopharmaceuticals are detected by special types of cameras that work with computers to provide very precise pictures about the area of the body being imaged. In treatment, the radiopharmaceuticals go directly to the organ being treated. The amount of radiation in a typical nuclear imaging procedure is comparable with that received during a diagnostic X-ray, and the amount received in a typical treatment procedure is kept within safe limits.

There are nearly 100 different nuclear medicine imaging procedures available. Every major organ system is imaged by nuclear medicine.
