We evaluated the physiological accumulation of bile in gallbladder using DCE-MRC obtained with Gd-EOB-DTPA. As the results, Twenty-seven of 75 patients (36%) were delayed type (Visualization of Gd-EOB-DTPA in the end of the common bile duct is earlier than that of gallbladder), and remaining 48 (64%) were orthodromic type (Visualization of Gd-EOB-DTPA in the gallbladder is earlier than that of end of the common bile duct). The delay of the bile accumulation in the gallbladder is associated with T1 hyperintense bile or sludge of gallbladder, indicating the increase of viscosity and pressure in the gallbladder.
