Abstract
Positron emission tomography (PET) imaging has emerged as the most important component of medical imaging in the management of oncology patients. It is a functional imaging technique in which radioactive tracer distribution in tissues is projected as a computer-generated image. The image is produced through the detection of annihilation photons emitted by radionuclides, which decay by emission of positrons. PET imaging with F-18 FDG depends on alteration in glucose metabolism of tissues for detection of disease. It differs from conventional imaging techniques that rely on morphologic changes for disease detection. As glucose metabolism is increased in many malignancies, F-18 FDG PET is a sensitive method for detecting, staging, and monitoring the effects of therapy in various malignancies.
