Figure 2 Visual evaluation of portal blood vessels by three-dimensional (3D) computed tomographic angiography with computed tomographic colonography (3D-CTA with CTC). 3D-CTA with CTC in a 51-year-old man with sigmoid colon cancer. Arrows indicate vessels for image evaluations. The average CT values and average scores according to the 7-point scale from 0 to 6 according to visibility were, respectively, as follows: superior mesenteric vein (SMV), CT value 211.6 Hounsfield units [HU], 5.3 points; inferior mesenteric vein (IMV), 253.0 HU, 5.7 points; left colonic vein (LCV), 220.0 HU, 3.3 points; and sigmoidal vein (SV), 207.4 HU, 3.3 points.
