Normal colon

 

Colonic activity is extremely variable in location and intensity. Activity typically involves the bowel walls but at times appears to be intraluminal. Colonic activity is generally more intense than that in the small bowel. Because of the high variability of activity in the colon, detection of colonic pathology is difficult. As a general rule, a single focus or multiple foci of activity clearly more intense than other colonic activity should be considered suspicious and a diligent search for evidence of pathology on the CT images should be made. If inconclusive, the interpreter would recommend clinical correlation followed by dedicated colonic examination (e.g. colonoscopy or barium enema) if indicated.
