Excerpt

Positron emission tomography–computed tomography (PET-CT) scans with [18F]-fluorodeoxyglucose (FDG) and PET–magnetic resonance imaging (MRI) have become standard practice in staging and restaging of colorectal cancer patients by providing important information about the primary cancer as well as metastases. The PET portion of this imaging modality relies on the accumulation of radioactive glucose analog, FDG. In cancer cells, there is an overproduction of glucose transporters and, as a result, increased FDG uptake. However, not all PET-positive lesions are cancer, and in many instances, PET findings can be false positive. …
