Figure 3 Values obtained by three-dimensional (3D) computed tomographic angiography with computed tomographic colonography (3D-CTA with CTC) and 3D computed tomographic angiography (CTA) for the arterial phase. The average CT values for 3D-CTA with CTC were significantly superior to those with 3D-CTA in left colonic artery (LCA) (3D-CTA, 228.5±44.4 Hounsfield unit [HU]; 3D-CTA with CTC, 269.7±56.2 HU; P=0.045) and sigmoidal artery (SA) (3D-CTA, 170.2±44.1 HU; 3D-CTA with CTC, 209.8±60.4 HU; P=0.034). Statistical analyses were performed at a significance level of 0.05 by using the Mann-Whitney U test.
