Colorectal cancers can be found anywhere from the cecum to the rectum. Rectosigmoid involvement includes about 55% of cases as the most common site of colorectal cancer. CT is the modality most used for staging colorectal carcinoma, however, MRI is the preferred modality for the staging of rectal cancer.
