The Utility of Mesenteric T1 Mapping on MR Enterography in Crohn's Disease: A Preliminary Study.

ABSTRACT: Background: Crohn's disease (CD) is a chronic disorder characterized by transmural bowel wall involvement and mesenteric changes, including inflammation and fibrosis. Although Magnetic Resonance Imaging (MRI)-based scoring systems have been proposed for the quantitative assessment of bowel wall changes in Magnetic Resonance enterography (MRE), there has been limited discussion regarding methods for the quantitative evaluation of mesenteric involvement. T1 mapping is an emerging MRI technique, potentially reflecting inflammation and fibrosis. This study aimed to assess the clinical utility of mesenteric T1 mapping in patients with CD. Methods: We retrospectively analyzed 71 adults with CD who underwent MRE from October 2024 to May 2025. Mesenteric native T1, post-contrast T1 r
