Magnetic resonance cholangiopancreatography (MRCP) is an effective imaging modality for the evaluation of anatomy and abnormalities of biliary and pancreatic system. The main drawback of conventional navigator-triggered (NT) MRCP is the long acquisition time resulting in a greater variability in the depth of respiration, which may create image blurring and motion artifacts. In this study, we performed MRCP scanning using a single breath hold (BH) 3D SPACE and NT SPACE protocols to evaluated the image quality and acquisition time in patients with choledocholithiasis.
