The maximum diameter of transverse, and sigmoid colon and rectum was measured in the coronal or axial plane. The appearance of whole colon was assessed on T1-weighted sequence (Thin‐slice gradient‐echo, 1.5T) of MRI. Results The mean values of the diameter of transverse and sigmoid colon and rectum were 3.7±1.0mm, 5.7±1.4mm and 6.5±1.3mm, respectively. In 3 cases, it is difficult to identify transverse colon. Microcolon was detected on MRI and the signal intensity of the intraluminal fluid in the dilated bowel were high on T1w sequences (Figure 1a-d). Remaining 18 cases were transient bowel dilation and microcolon was not detected (Figure 2a-d). Discussion
