Cure8 research brief
Baseline MRE features may help predict which Crohn's strictures will not improve with advanced medical therapy, informing monitoring and surgical planning. Better stratification could guide decisions about earlier surgical referral or closer follow-up.
Clinicians managing Crohn's disease strictures, radiologists, IBD surgeons, researchers studying imaging biomarkers, and patients with Crohn's disease considering or on advanced therapies.
The authors developed two MRE-based scores in a development cohort and validated them in a later cohort. The A-score included bowel wall thickness >6 mm, ulceration, and comb sign; the P-score included stricture length >3 cm, prestenotic dilation >3 cm, and absence of intramural edema.
Each score independently predicted lack of stricture improvement on follow-up MRE, and the summed A+P score showed better discrimination (AUC 0.90) than other segmental MRI indices. Higher P-scores correlated with persistently low improvement rates and baseline strata were associated with differences in surgery-free survival.
How patients might use this: For people with Crohn's strictures undergoing baseline MRE before or when starting advanced therapy, these imaging features may help clinicians estimate the chance a stricture will persist and discuss likely need for surgery.
This framework is meant as an imaging severity and risk-stratification tool, not a direct test of whether a stricture is inflammatory versus fibrotic.
This report is an abstract-summary level clinical study with development and temporal validation cohorts; findings describe associations and risk stratification but do not establish treatment-effectiveness decisions. The authors emphasize the tool is for baseline imaging severity/risk stratification rather than labeling strictures as inflammatory versus fibrotic.

People with Crohn’s disease who have an ileostomy have limited noninvasive ways to monitor small-bowel inflammation. This study suggests measuring fecal calprotectin from ileostomy output could help detect postoperative...
Risk stratification helps identify people with Crohn's who are more likely to develop strictures, fistulas, or need surgery so clinicians can monitor and treat them more aggressively early on. Objective tests like fecal...
New PET tracers like FAPI could better detect fibrosis and stromal activity than standard FDG-PET, which may improve imaging of fibrostenotic Crohn's disease. For people with IBD, improved imaging might eventually help...
