Nuclear Medicine Scientists (also known as Nuclear Medicine Technologists) are highly skilled health experts who use very small quantities of radionuclides to diagnose diseases — by detecting physiological and metabolic changes within the body and using the same principles to treat diseases. A career in nuclear medicine combines the humanities of patient care, sociology of health, cutting-edge science (instrumentation and computing) with health/medical science. Get qualified to deliver radionuclide therapies and to provide diagnosis using a gamma camera, SPECT, PET, SPECT/CT, PET/CT, PET/MRI and CT.
