Many physicians in fields including cardiology, neurology, and oncology use PET … A positron emission tomography scan is a type of imaging test. This is different than MRI and CT scans. Positron emission tomography (PET) scans are used to produce detailed 3-dimensional images of the inside of the body. It involves the injection of a short-acting radioactive substance, known as a radiotracer, which is absorbed by biologically active cells. A heart positron emission tomography (PET) scan is an imaging test that uses a radioactive substance called a tracer to look for disease or poor blood flow in the heart.

Those abbreviations stand for: fluorodeoxyglucose (FDG)-positron emission tomography (PET). It gives detailed information about your cancer. A PET scan alone can verify that even small masses are cancerous because the technique uses a type of sugar, or glucose, that glows. Positron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, … Your healthcare provider may perform a PET scan and CT scan at the same time (PET-CT). : (209) 365-1761: Scans Performed: 311 S Ham Lane Lodi, CA 95242: Long Beach PET Imaging Center: Tel.

PET emission data traditionally have been acquired for 4 min per bed position. Single-photon emission computed tomography (SPECT, or less commonly, SPET) is a nuclear medicine tomographic imaging technique using gamma rays. The radioactivity used in a PET scan is attached to glucose and shows metabolism, in the brain normal metabolism and brain activity shows up as dark areas, with loss of brain function (e.g. A positron emission tomography (PET) scan shows how organs and tissues are working. A PET scan uses small amounts of radioactive substances, called contrast materials, for contrast within the body. PET scan is a type of test that may be used in cancer treatment. PetScan (previously CatScan) is an external tool that searches an article category (and its subcategories) according to specified criteria to find articles, stubs, images, and categories.
