Example of DWI in active inflammation: a axial T1 fat-saturated post-contrast image shows thickened enhancing ileum with typical stratified enhancement pattern (arrow); b corresponding DWI (b = 800) and c ADC map confirm restricted diffusion with persistent high signal (arrow) on the DWI and low signal (arrow) on the ADC map (ROI = 1,200)
