Quantitative MRCP Imaging: Accuracy, Repeatability, Reproducibility, and Cohort‐Derived Normative Ranges

Abstract Background: Magnetic resonance cholangiopancreatography (MRCP) is an important tool for noninvasive imaging of biliary disease, however, its assessment is currently subjective, resulting in the need for objective biomarkers. Purpose: To investigate the accuracy, scan/rescan repeatability, and cross‐scanner reproducibility of a novel quantitative MRCP tool on phantoms and in vivo. Additionally, to report normative ranges derived from the healthy cohort for duct measurements and tree‐level summary metrics. Study Type: Prospective. Phantoms/Subjects: Phantoms: two bespoke designs, one with varying tube‐width, curvature,
