 Colorectal cancer is one of the tumors that shows strong accumulation of FDG. But due to the limitation of spatial resolution, small cancer is difficult to detect on PET. Detectability of early colorectal cancer is also inadequate on PET, especially a tumor showing flat type is difficult to depict though polypoid type is sometimes revealed as a hot spot of FDG accumulation.

 A recent report from Japan, that analyzed nationwide multi-institutional data, described the usefulness of “FDG-PET cancer screening”. In this report, colorectal cancer was the most frequently found malignancy. This report showed notable evidence that FDG-PET have a definite role to play in cancer survey, though epidemiological evidence based on high-level studies are still inadequate.
