Commonly referred to as PET, positron emission tomography is an examination that allows the physician to study the abnormalities of the heart and brain, as well as identify primary and metastatic disease. With its unique imaging technique, PET is capable of detecting certain diseases at an early stage in cellular functioning. A PET scan will provide information that can be used in the planning and management of care, in determining therapy and progress to therapy.
