Abstract

Positron emission tomography (PET) [1] is a tomographic technique of nuclear medicine in which a computer-generated image of local radioactive tracer distribution in tissues is produced through the detection of annihilation photons emitted when radio-nuclides introduced into the body decay and release positrons. PET with 18F-fluorodeoxyglucose (18F-FDG) uses a radio-labeled analog of glucose to image relative glucose metabolic rates in various tissues. Because glucose metabolism is increased in many malignancies, 18F-FDG PET is a sensitive method for detecting, staging, and monitoring the effects of therapy of many tumors. Computed tomography (CT) is a tomographic imaging technique that uses an X-ray beam to produce anatomic images. This anatomic information is used to detect and help to determine the location and extent of malignancies. Combined PET/CT devices provide both the metabolic information from PET and the anatomic information from CT in a single examination. As shown in some clinical experiences, the information obtained by PET-CT appears to be more accurate in evaluating patients with known or suspected malignancies than does the information obtained from either PET or CT separately and interpreted side by side.
