How does the pet scan work
WebPET scanners work by detecting the radiation given off by a substance injected into your arm called a radiotracer as it collects in different parts of your body. In most PET scans a radiotracer called fluorodeoxyglucose (FDG) is used, which is similar to naturally occurring glucose (a type of sugar) so your body treats it in a similar way. WebHow does a PET-CT scan work? Before your PET-CT scan, you will get an injection of a small amount of a radioactive sugar called fluorodeoxyglucose-18.
