Dhafer A. Deeab, Elizabeth Dick, Antoni A. Sergot, Lauren Sundblon, Wady Gedroyc  Radiography  Volume 17, Issue 1, Pages (February 2011) DOI: /j.radi Copyright © Terms and Conditions

2 Fig. 1 (a) (Coronal fat saturated follow through) showing normal findings. (b) (Axial T2 fat saturated follow through) showing normal findings. Radiography  , 67-71DOI: ( /j.radi ) Copyright © Terms and Conditions

3 Fig. 2 (Post-gadolinium, fat saturated coronal) showing normal bowel wall thickness (with up to 3mm of luminal distension). Radiography  , 67-71DOI: ( /j.radi ) Copyright © Terms and Conditions

4 Fig. 3 (a) (Coronal T2 FIESTA) showing skip lesions which are concentric, symmetrical or asymmetrical (pseudo sacculation). (b) showing inflammatory mesenteric stranding within the distal ileum (yellow arrow). (c) (Post-Gadolinium) showing wall thickening (yellow arrow), stratified enhancement, ‘Comb sign’ –mesenteric hyperaemia (red arrow) and lymph nodes (green arrow). (d) (Axial T2 FIESTA) showing concentric, asymmetrical bowel wall thickening. Radiography  , 67-71DOI: ( /j.radi ) Copyright © Terms and Conditions

5 Fig. 4 (a) (Coronal FIESTA) showing large featureless dilated small bowel in the proximal jejunum which narrows inferiorly to a strictured segment. There is fat hypertrophy of the adjacent mesentery, which is typical of Crohn’s. (b) (post-Gad) showing contrast enhancement of the inflammatory stricture.

6 Fig. 5 (a) (Coronal FIESTA) and (b) (axial FIESTA) showing circumferential thickening of the proximal Jejunum due to adenocarcinoma. (c) showing intense contrast enhancement of the tumour. Radiography  , 67-71DOI: ( /j.radi ) Copyright © Terms and Conditions

7 Fig. 6 (Axial T1WI) showing the creeping fat hypertrophy associated with chronic Crohn’s disease. Radiography  , 67-71DOI: ( /j.radi ) Copyright © Terms and Conditions
