The sensitivity of CT in detecting colorectal cancer was 100% (95% confidence interval [CI]: 19.8–100%) and the specificity was 95.7% (95% CI: 88.8–98.6%). The positive predictive value was 33.3% (95% CI: 6.0–75.9%) and the negative predictive value was 100% (95% CI: 94.8–100%).

How does colon cancer appear on CT?
