Feasibility of gadoxetate disodium enhanced 3D T1 MR cholangiography (MRC) with a specific inversion recovery prepulse for the assessment of the hepatobiliary system - Fig 4

Maximum intensity projection images of the biliary system (a, c: T2 MRCP, b, d: T1 MRC). 53 year-old female patient examined due to suspected focal nodular hyperplasia (black arrowhead in T1 MRC, not visible on T2 MRCP). As contrast in T1 MRC is given by gadoxetate disodium, the pancreatic duct visualized on T2 MRCP (white arrow) is not visualized T1 MRC. Please also note improved conspicuity of the intrahepatic bile ducts on T2 MRCP compared to T1 MRC, which can also be seen on in a 30 year-old female patient (c, d) who was examined due to suspected intrahepatic choledocholithiasis (white arrowheads) which could be verified with MR.
