Inflammatory chronic disease of the colon: How to image Roberta Ambrosini, Annalisa Barchiesi, Veronica Di Mizio, Marco Di Terlizzi, Luca Leo, Antonella Filippone, Luigi Canalis, Rita Fossaceca, Alessandro Carriero European Journal of Radiology Volume 61, Issue 3, Pages 442-448 (March 2007) DOI: 10.1016/j.ejrad.2006.07.028 Copyright © 2006 Elsevier Ireland Ltd Terms and Conditions

Fig. 1 Early UC. The double-contrast barium enema shows a fine granular appearance in the rectum (white arrow), without ulceration of the mucosa. European Journal of Radiology 2007 61, 442-448DOI: (10.1016/j.ejrad.2006.07.028) Copyright © 2006 Elsevier Ireland Ltd Terms and Conditions

Fig. 2 UC. The double-contrast barium enema shows a diffuse granular appearance of the colonic mucosa, consistent with acute pancolitis. European Journal of Radiology 2007 61, 442-448DOI: (10.1016/j.ejrad.2006.07.028) Copyright © 2006 Elsevier Ireland Ltd Terms and Conditions

Fig. 3 Early CD. The double-contrast barium enema shows multiple colonic segments characterized by mucosal punctate collections of barium surrounded by radiolucent halo of edema consistent with aphthous ulcers.

Fig. 4 Crohn's colitis of right colon. Transverse US examination shows target sign in a loop of the right colon. European Journal of Radiology 2007 61, 442-448DOI: (10.1016/j.ejrad.2006.07.028) Copyright © 2006 Elsevier Ireland Ltd Terms and Conditions

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.

Fig. 6 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).

Fig. 7 Complicated Crohn's colitis. The double-contrast barium enema shows multiple tracks and a colo-colic fistulas, with fibrosis and pseudo-diverticula (white arrows).
