Abstract
Symptoms suggestive of colorectal cancer are nonspecific and common in the general population; only 5% of patients investigated have colorectal cancer (1). Diagnosis should be safe and acceptable because most of those tested have no abnormalities detected. Colonoscopy is widely regarded as the reference standard test for colorectal neoplasia, combining accuracy with efficiency because diagnosis and polypectomy can be combined. Colonoscopy, however, can be uncomfortable, requires analgesia and/or sedation, and carries some risks (2), particularly in older patients. Computed tomographic (CT) colonography is possibly more acceptable to patients (3,4) and relatively safe (5), while maintaining sensitivity for cancer. A recent meta-analysis showed a mean sensitivity of 96% for CT colonography versus 95% for colonoscopy (6).
