Zusammenfassung
Purpose: Aim of this study was to investigate the feasibility of 7.0 Tesla ultra highfield MR imaging of the kidneys, with the implementation of a dedicated examination protocol utilizing a custom-built 8-channel body coil. Materials and Methods: In vivo examinations were performed in 8 healthy volunteers on a 7T whole-body MR system (Magnetom 7T, Siemens Healthcare). The following non-enhanced sequences were obtained using a custom-built 8-channel transmit/receive radiofrequency body coil suitable for RF-shimming: 1) T1w fat-saturated 2D FLASH 2) T1w 2D in and opposed phase 3) True-FISP 4) T2w TSE.
