Figure 1 Visual evaluation of arterial blood vessels using three-dimensional (3D) computed tomographic angiography with computed tomographic colonography (3D-CTA with CTC). 3D-CTC with CT angiography in a 63-year-old man with ascending colon cancer. Arrows indicate each vessel for image evaluations. The average CT values and average scores according to a 7-point scale from 0 to 6 in ascending order of visibility were as follows: superior mesenteric artery (SMA), CT value 418 Hounsfield unit [HU], 6 points; middle colic artery (MCA), 369.2 HU, 5 points; right colonic artery (RCA), 353.0 HU, 5 points; and Ileocolic artery (ICA), 355.6 HU, 4.7 points.
