| There were no significant differences in sex, age, height, weight, body mass index (BMI), and tumor location between the 3D-CTA and 3D-CTA with CTC groups. Age, height, weight, and BMI were analyzed at a significance level of 0.05 using the Mann-Whitney U test. Sex and tumor location were statistically analyzed at a significance level of 0.05 using Fisher’s exact test. 3D-CTA – three-dimensional computed tomographic angiography; 3D-CTA with CTC – three-dimensional computed tomographic angiography with computed tomographic colonography; SD – standard deviation. | ||
