What is PET/CT?
PET/CT is a modality within Nuclear Medicine which combines a PET scanner and a CT scanner within a single gantry.
Nuclear Medicine is considered ‘Functional Imaging’; it obtains images of how the body functions. Most often, Functional Imaging requires the injection of a radiopharmaceutical (radioactive drug) designed to look for specific functions in the body, such as metastatic cancer. Functional Imaging can often detect abnormalities in the body much sooner than other imaging techniques. It can detect an abnormality prior to it becoming an invasive tumor.
