This new study explores the feasibility of using a single-channel mechanically Rotating RF Coil (RRFC) for flip angle (FA) and specific absorption rate (SAR) management applications at 7T MRI. Compared to the 8-channel Parallel Coil Array, RRFC yielded a much more uniform FA distribution and a lower SAR. This initial study suggests that RRFC may be very useful in alleviating the FA and SAR issues associated with contemporary high field MRI.
