Dynamic Contrast-Enhanced MR with Quantitative Perfusion Analysis of Small Bowel in Vascular Assessment between Inflammatory and Fibrotic Lesions in Crohnʼs Disease: A Feasibility Study

Figure 4

A 45-year-old man with known active disease characterized by the presence of mural thickening of last ileal bowel loop characterized by mild hyperintensity in the T2-weighted images (arrowhead in (a) and (b)), layered enhancement in dynamic study (arrowhead in (c)), and vascular congestion associated (arrow). The perfusion analysis allows highlighting the pathological segment in the color map (d), and the time-intensity curves demonstrate an increasing trend of enhancement for pathological loops.
