Mesenteric and antimesenteric border subregionalization using MR enterography: advancing fibrosis evaluation in Crohn disease

Key Points

• The aim is to enhance the evaluation of intestinal fibrosis in Crohn disease through improved subregional analysis.
• Conducted MR enterography for fibrosis assessment in Crohn disease patients.
• Compared whole-region analysis with subregional analysis focusing on mesenteric and antimesenteric borders.
• Evaluated the impact of mesenteric border fibrosis severity on disease progression.
• Subregional analysis showed superior accuracy in detecting fibrosis compared to whole-region analysis.
• Fibrosis was significantly more severe in the mesenteric border than in the antimesenteric border.
• Baseline mesenteric border fibrosis severity was the strongest predictor of disease progression.
