Nuclear Medicine and Positron Emission Tomography (PET) use specialized radioactive material, injected into the body, to view cellular function. This radioactive substance travels through the body and gathers in the organs and tissues. Imaging technology can be used to view the energy given off by the nuclear tracer to identify conditions that may otherwise be impossible to detect.

PET/CT produces three-dimensional images to view the body's internal functions. Unlike CT and MRI, which only look at anatomical structure, PET scans detect gamma rays to reveal the metabolic function within the body before anatomical changes take place. The CT scan provides information about the body's anatomy such as size, shape and location. By combining these two scanning technologies, a PET/CT scan enables physicians to more accurately diagnose and identify cancer, heart disease and brain disorders.

Nuclear medicine is a non-invasive and painless way to diagnose and treat a variety of diseases. The small amount of radioactive material is flushed from the body in one to two days. Nuclear medicine scans are among the safest diagnostic imaging tests with no risk of side effects or allergies.
