Development of a simplified model and nomogram in preoperative diagnosis of pediatric chronic cholangitis with pancreaticobiliary maljunction using clinical variables and MRI radiomics

Abstract

Key points Conventional imaging modalities were not powerful enough to diagnose chronic cholangitis. The radiomics signature based on T2-weighted MR images performed well in diagnosing chronic cholangitis. Associating the radiomics signature with clinical factors improved the diagnosis performance of chronic cholangitis.
