Aim of this study was to investigate the feasibility of 7 Tesla liver MRI, with optimization and implementation of a dedicated examination protocol. 8 healthy subjects were examined at a 7T whole-body MR system utilizing a custom-built 8-channel RF transmit/receive body coil. Delineation of liver vessels, overall image quality and presence of artifacts was assessed. T1w imaging revealed very good delineation of liver vasculature, with best imaging scores for T1w 2D FLASH imaging. T2w TSE imaging remained strongly impaired by artifacts. This pilot study of dedicated hepatic imaging at 7 Tesla demonstrates the feasibility of in vivo ultra-high-field liver imaging.
