Interobserver agreement between radiologists was 64% for fecal contamination (kappa = 0.18, SE = 0.05; p\u2009&lt;\u20090.001). In 7 of 12 patients who turned out to have colon cancer, this was suspected at CT by at least one radiologist (sensitivity = 58%, specificity = 91%, PPV = 29%, NPV = 97%).
