IMAGING - Magnetic Resonance Imaging (MRI)

An objective demonstration of the presence and severity of inflammatory lesions is essential to optimizing and personalizing the management of inflammatory bowel diseases. Endoscopy has for many years been the gold standard for objectively assessing disease activity. In recent years, our group has shown that MRI can provide an accurate and reliable assessment of intestinal inflammatory lesions, and is superior to endoscopy in terms of assessing stricturing and penetrating complications. We have derived and validated a quantitative index of activity for Crohn’s disease, and shown that it is responsive to therapeutic interventions, thus making it a useful tool for clinical practice and for clinical trials.

Endoscopic Image: The sagittal volumetric interpolated breath hold examination (VIBE) shows the descending colon until the splenic angle. The VIBE 1 shows ulcers in the transvers colon until the hepatic angle. The image also shows a healthy ascending segment and a part of affected ileum.

We are further developing MRI-based applications to study inflammatory intestinal lesions to increase both the accuracy and tolerability of the examination for patients and radiologists, minimizing the preparation and time required. We are also developing new modalities to measure fibrosis in intestinal segments affected by Crohn’s disease, information that may have a considerable impact on patient management and that could facilitate the development of antifibrotic drugs.
