We compared the depiction of the cystic duct between two types of 3D breath-holding MRCP accelerated with GRASE (GRASE-MRCP) and FSE with compressed sensing (CS-MRCP) at 1.5T. Although imaging time and overall image quality was the same, breath-hold MRCP accelerated with GRASE allowed better depiction of the cystic duct as compared with FSE MRCP with CS because shorter TE with GRASE allowed higher signal of the concentrated bile.
