Nuclear medicine technologists use safe, painless and cost-effective techniques to image the body and treat disease. Nuclear medicine uniquely provides information about the structure and function of virtually every major organ system within the body. It is this ability to characterize and quantify physiologic function at the molecular level, which separates nuclear medicine from other imaging modalities. With the development of new radiopharmaceuticals, treatments and the exciting technology of Positron Emission Tomography/Computed Tomography (PET/CT) hybrid imaging, the nuclear medicine field has grown significantly over the past years and is expected to grow even more in the future. Daily tasks of a nuclear medicine technologist include:
