Objective To evaluate the diagnostic value of DWI signal intensity(SI)and ADC for inflammatory activity in ileocolonic Crohn disease(CD).Methods The MR enterography(MRE)and DWI data were retrospectively analyzed in 42 patients with CD confirmed by endoscopic and pathological examination.The segment disease activity was scored by a simplified endoscopic score for Crohn disease(SES-CD)and was graded as inactive(1 to 2),mild(3 to 6)or moderate-severe inflammation(≥7).
