An 8-channel transmit/15-channel receive radiofrequency coil setup for 7T shoulder imaging has been evaluated in eight patients presenting with shoulder pain. In total, ten gradient echo and turbo spin echo sequences were included in the imaging protocol. Image quality was assessed in consensus by two radiologists. A structured report focusing on the rotator cuff was generated based on the 7T images and subsequently compared with the arthroscopical report taken as the gold standard. Finally, pathologies found at 7T were visually compared with preexisting 1.5T MR images from the same patients.
