This study evaluated the visibility and diameter of the pancreatic duct (PD) and common bile duct (CBD) on 2D MR images in children without pancreaticobiliary disease. Reviewing 177 patients, the study found variability in PD visibility across different segments, with maximum PD diameter ranging from 0.7 to 3.5 mm, and CBD diameter from 2.9 to 3.4 mm. The research provides expected upper limits for these duct measurements, aiding radiologists in identifying potential abnormalities on routine abdominal MRIs.
