1 Magnetic resonance enteroclysis in patients with Crohn's disease: Fat saturated T2- weighted sequences for evaluation of inflammatory activity  Christian Grieser, Timm Denecke, Ingo G. Steffen, Scarlett Werner, Thomas Kröncke, Olaf Guckelberger, Ulrich-Frank Pape, Johannes Meier, Regina Thiel, Dietmar Kivelitz, Andreas Sturm, Bernd Hamm, Rainer Röttgen  Journal of Crohn's and Colitis  Volume 6, Issue 3, Pages (April 2012) DOI: /j.crohns Copyright © 2011 European Crohn's and Colitis Organisation Terms and Conditions

2 Figure 1 31 year-old female patient suffering from Crohn's Disease (Crohn's Disease Activity Index, 380) with endoscopically confirmed acute inflammatory activity in the ascending colon (white arrows) showing concordant findings on (A) contrast enhanced T1-weighted images (activity score, grade 4; T1-ratio, 2.83) and (B) T2-weighted images (grade 4; T2-ratio, 2.8).

3 Figure 2 47 year-old female patient suffering from Crohn's Disease without symptoms of acute inflammatory activity (Crohn's Disease Activity Index, 50) demonstrating (A) a contrast enhancing lesion on T1-weighted images (grade 4; T1-ratio, 4.7) in the distal ileum (white arrows). The lesion was negative on (B) T2-weighted images (activity score, grade 2; T2-ratio, 1.74) and confirmed to be free of acute inflammation endoscopically.
