Nuclear Medicine - Career Opportunities Nuclear medicine is a medical specialty that uses very small amounts of radioactive materials to diagnose and treat disease. Diagnostic nuclear medicine can provide information about the function of nearly every organ in the body. Nuclear medicine procedures often identify problems early in the disease process, long before they are apparent with other diagnostic tests. These studies are often used in conjunction with computed tomography (CT) to provide three-dimensional views of organs and the location of problems within the organ. The nuclear medicine technologist is a healthcare professional who works closely with nuclear medicine physicians and cardiologists. Responsibilities of the nuclear medicine technologist include: preparation and administration of radioactive materials; performing patient care during nuclear medicine imaging and therapy procedures; managing computer processing and image manipulation; and providing patient information and images to the physician for diagnosis. Demand for nuclear medicine technologists in many healthcare settings -- including hospitals, clinics, doctors' offices or imaging centers -- is strong across the country. The exciting and dynamic field of nuclear medicine is constantly changing and career opportunities continue to expand, providing job opportunities with competitive salaries and benefits. A career in nuclear medicine technology provides a variety of opportunities. Nuclear medicine technologists may choose to specialize in PET scanning or nuclear cardiology. They may continue their education to obtain an advanced degree in pursuit of a career in education, management, or research.
