Close up coronal views showing subtle details in SB walls. a Abdominal window setting (WW 400 HU, WL -15 HU) and 0.7 mm thin-slice reconstruction showing mucosal folds. b Lung window setting (WW 2,000 HU, WL -400) and 0.7 mm thin-slice reconstruction showing SB filled with Lumentin 44 and part of sigmoid colon containing air. c Abdominal window setting (WW 400 HU, WL -15 HU) and 5 mm thick-slice reconstruction showing terminal ileum entering the caecum.
