​Nuclear medicine is a branch of radiology that uses small amounts of administered radiopharmaceuticals to image the body, and at times it is used to treat certain types of disease. What makes nuclear medicine unique is that it provides doctors with information about both structure and function and can be done with planar and three-dimensional imaging. 

Nuclear medicine offers procedures that are essential in a variety of medical specialties, delivering the same amount of radiation in a typical exam as a diagnostic X-ray.
