3T MRI and parallel imaging techniques make quality 3D sequences for magnetic resonance cholangiopancreatography (MRCP) clinically feasible. In this study, 20 patients underwent MRCP that included standard 2D thick-slab SSFSE images and 3D breath hold (BH) and 3D respiratory gated non-breath hold (RG-NBH) FRFSE sequences on a 3T GE system. Image sets were evaluated for visualization of different levels of bile ducts, pancreatic ducts, SNR, and overall impression. 3D RG-NBH was significantly better than 2D thick-slab SSFSE for depicting most bile ducts, SNR, and overall impression. 3D RG-NBH significantly outperformed 3D BH in all categories.
