 Currently, FDG(fluorodeoxyglucose)-PET(positron emission tomography)is being used to determine the stage of colorectal cancer, particularly screening of distant metastases, and to detect recurrence. Because FDG-PET is being covered under reimbursement since 2010 for all malignancies except early gastric cancer, it can be used for small intestinal cancer and non-epithelial tumors. Colorectal cancer is the most frequently found cancer in cancer screening programs that include FDG-PET. FDG-PET is a useful modality for cancer screening because the sensitivity of FDG-PET is superior to that of the FOBT(fecal occult blood test). The response to molecular target therapy is closely correlated with gene mutations, and FDG-PET is suggested to be a promising imaging biomarker that reflects therapeutic effect.

 Although therapeutic monitoring and response prediction by FDG-PET are not currently covered under reimbursement, the available applications of PET will expand if supportive evidence is collected in the near future.
