Figure 6 Evaluation of visibility according to 7-point scale in ascending order of visibility in the portal phase. Scores obtained by three-dimensional (3D) computed tomographic angiography with computed tomographic colonography (3D-CTA with CTC) indicated significantly superior image quality than those obtained by 3D-computed tomographic angiography (CTA) for the middle colonic vein (MCV), P=0.049; ileocolic vein (ICV), P=0.049; inferior mesenteric vein (IMV), P=0.001; left colonic vein (LCV), P<0.001; sigmoidal vein (SV), P=0.003; and superior rectal vein (SRV), P<0.001. Statistical analyses were performed at a significance level of 0.05 by using the Mann-Whitney U test.
