 The effectiveness of FDG PET/CT in screening for colorectal cancer has been reported, but its use is inappropriate owing to the radiation exposure and high cost associated with it. The sensitivity of PET for advanced neoplasms is 15-16%. PET/CT can detect advanced colorectal cancer well, but it has some limitations with respect to the tumor volume and background. Detection of small lesion and differentiation to cancer from inflammation are sometimes difficult.

 Therefore, diagnosis with PET/CT is inappropriate in case of colorectal cancer. PET/CT screening has not reduced the mortality rate of the colorectal cancer. It is necessary to establish an effective screening program including PET/CT.
