6. Fig. 5
Crohn's colitis. The double contrast barium enema (a) shows a focal narrowing (white arrow) of the right colon, with loss of lumen distensibility and a “cobblestone pattern”. Contrast-enhanced CT shows, both on the axial plane (b) and on the coronal multiplanar reformation (c) the presence of focal circumferential wall thickening (>1cm) with homogeneous enhancement after intravenous administration of contrast medium (black arrows on b and c) and pericolonic stranding.

Active UC. Dark lumen MR colonography (a), carried out using T1w 3D THRIVE sequences after Gd-DTPA i.v. injection, shows high contrast-enhancement of the rectum, sigmoid and left colonic walls (white arrow in a), that show a loss of haustral folds; a little perivisceral fluid collection is also appreciable on the bright lumen 3D BTFE image (white arrow in b).
