  		Fig. 3C. —61-year-old man with false-positive findings for colonic polyp. Narrow-window-setting transverse CT colonography image shows tiny gas bubble at center of elevated lesion (arrow); this finding confirmed presence of residual fecal material. No polyp was seen on colonoscopy.

  		Fig. 5A. —48-year-old woman with overstaged T2 colon cancer. Axial (A) and sagittal (B) reformatted images clearly show irregular rectal mass with perirectal fat stranding (arrows). Initial preoperative diagnosis was T3 lesion, but lesion proved to be T2.
