MR imaging of the liver was investigated at 7 Tesla using Gadoxetic acid for depiction of the intra- and extrahepatic biliary tract. A custom-built eight-channel RF transmit/receive body coil and RF shimming were used. In 10 healthy volunteers, dynamic T1-weighted 3D VIBE and 3D FLASH inversion recovery sequences were acquired in the hepatobiliary phase. For comparison, all volunteers underwent a conventional T2-weighted MRCP at 3T. Initial results demonstrate feasibility, showing both benefits and limitations of this technique.
