WebPET scans are often done along with CT scans (called a PET/CT scan) to give more definitive information about metabolism changes and exactly where they are happening in the body. PET works by using a special camera that detects positrons emitted by the radioactive tracer in the organ or tissue being examined. Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption. Different tracers are used for various imaging purposes, depending on the target process within the body. F… cynthia wesley autopsy
