Coronal (A) and (B) axial fat-suppressed post-gadolinium 3D-GRE T1-weighted images during the (A) arterial and (B) enteric in a patient with active Crohn’s disease. There is extensive mucosal enhancement involving the affected terminal ileum (arrows, A), reflecting active disease. Enteric phase images (B) shows serosal enhancement providing the tri-laminar appearance of active disease (arrows, B). GRE: Gradient recalled echo.
