Overview
CT scan is not routinely used for the diagnosis of hereditary nonpolyposis colorectal cancer. However, in some cases, CT scan can be useful in the detection of extracolonic lesions and also right-sided colon lesions (especially in the cecum) which are not easily seen with colonoscopy.
CT scan
- CT scan is not routinely used for the diagnosis of hereditary nonpolyposis colorectal cancer.
- However, in some cases, CT scan can be useful in the detection of extracolonic lesions and also right-sided colon lesions (especially in the cecum) which are not easily seen with colonoscopy.[1][2]
- Although CT scan has an acceptable accuracy for detecting large lesions in the colon but it has poor sensitivity in detecting small polyps. Therefore CT scan remains a good alternative in surveillance when colonoscopy is deemed incomplete or unsuitable.[3][4]
