What is Nuclear Medicine?
Nuclear medicine technologists use safe, painless, and cost-effective techniques to image the body and treat disease. Nuclear medicine imaging is unique, because it provides doctors with information about both structure and function. It is a way to gather medical information that would otherwise be unavailable, require surgery, or necessitate more expensive diagnostic tests. Nuclear medicine imaging procedures often 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 (radiopharmaceuticals) to diagnose 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. The amount of radiation in a typical nuclear imaging procedure is comparable with that received during a diagnostic x-ray.
