From: A closer look at the stoma: multimodal imaging of patients with ileostomies and colostomies
Normal appearance of ileostomies at MR-enterography in two patients operated for Crohn’s disease. a, b Axial fat-suppressed T2-weighted (a) and sagittal post-gadolinium fat-suppressed T1-weighted (b) images showing collapsed stomal tract (arrow) traversing the abdominal wall, with normal mural thickness and contrast enhancement comparable to that of other small bowel loops. c, d Axial T2- (c) and post-gadolinium fat-suppressed T1-weighted (d) images showing collapsed stomal tract (arrow), mild protrusion at external orifice (thin arrows), and abundant fluid flowing within stoma bag consistent with stomal patency
