Positron Emission Tomography (PET)

Positron Emission Tomography (PET) is a diagnostic tool that uses radioisotopes to image the body's biochemical functions, detecting the presence, recurrence or spread of various types of cancer. Certain subtle changes in the body's biochemistry are indications of different types of cancers, including but not limited to colon cancer, breast cancer, lymphoma, lung cancer, and melanoma. PET scans go beyond the scope of MRI and CT images to reveal the disease process before visible signs and symptoms may occur. PET is also being utilized as a tool to identify early stage heart disease and brain disorders.
