MRCP accelerated with GRASE (GRASE-MRCP) allowed single breath-holding 3D MRCP and better depiction of the cystic duct because of short TE. On the other side, background signal such as blood vessels sometimes remained. Incorporating MSDE into GRASE-MRCP made it possible to suppress the background signals without extending the image time and reducing the image quality.
