Definition of age-dependent reference values for the diameter of the common bile duct and pancreatic duct on MRCP: a population-based, cross-sectional cohort study.

Objective: Changes of the pancreaticobiliary ducts herald disease. Magnetic resonance cholangiopancreatography (MRCP) allows accurate duct visualisation. Data on reliable upper reference ranges are missing.

Anatomic variants of the pancreatic duct and their clinical relevance: an MR-guided study in the general population.

Objectives: To investigate the frequency of pancreatic duct (PD) variants and their effect on pancreatic exocrine function in a population-based study using non-invasive secretin-stimulated magnetic resonance cholangiopancreatography (sMRCP).

Methods: Nine hundred and ninety-five volunteers, 457 women and 538 men, aged 51.9 ± 13.
