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).

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.
