Recent trends in the prevalence and distribution of colonic diverticula in Japan evaluated using computed tomography colonography

Figure 1 Detection of diverticula using computed tomography colonography. The diverticula were detected mainly in 2-dimensional (2D) supine axial images. If necessary, other 2D or 3-dimensional (3D) images were used. The arrow indicates a diverticulum. A: 2D-supine axial image; B: 2D-supine coronal image; C: 3D-virtual colonoscopy image.

Figure 2 Prevalence of diverticulosis by age group. The prevalence of diverticulosis increased with age (P < 0.001 for trend).

Figure 3 Location of diverticula by age group. An analysis of all participants showed that diverticulosis of the younger generation was predominantly right-sided, and bilateral diverticulosis increased with age (P < 0.001 for trend).
