Magnetic resonance enterography in Crohn’s disease: Standard and advanced techniques

Figure 4 Dynamic-contrast enhanced magnetic resonance imaging (DCE-MRI) findings in inflamed terminal ileum and in a normal segment. A: Coronal contrast-enhanced 3D GRE T1-weighted image shows wall thickening and increased enhancement of TI wall (arrow); B: Dynamic contrast-enhanced image showing ROI placed on inflamed terminal ileum (green ROI) wall and normal ileal segment (purple ROI); C: The time-intensity curves plotted as a function of time for terminal ileum and normal ileal segment. Perfusion parameters of TI (green curve) is higher than the normal ileal segments (purple curve); D: Color map generated from dynamic contrast enhanced study shows increased perfusion in terminal ileum (arrow).
