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 2

A case presenting with findings that do not allow classifying the disease as active or chronic; on the basis of the morphological sequences alone, there is an evident thickening of bowel ileal loop, not presenting hyperintensity in T2-weighted sequences (arrowhead in (a) and (b)), but with a slight vascular congestion (arrow in (c)) and a strong enhancement in dynamic study (arrowhead in (c)), that does present a very typical layered enhancement. The perfusion analysis demonstrates a time-intensity curves with an increasing trend of enhancement and higher perfusion values than those of the normal bowel, suggesting the presence of acute disease.
