Crohn's Disease Patients Undergoing Intestinal Resection
Patients with Crohn's disease undergoing planned intestinal resection surgery.
Resected intestinal specimens will be analyzed ex vivo using multiparametric magnetic resonance imaging, biophysical measurements (mechanical and electrical properties), and histopathological examination.
No experimental intervention is performed on participants beyond standard surgical care.
