Hamstring strains are the most frequent injuries in elite football. Currently, it is not possible to accurately predict recovery or recurrence risk, which motivates the development of improved leg muscle imaging methods and hardware. A novel 64-channel upper leg coil was designed and compared to a conventional coil in healthy volunteers using two clinical high-resolution muscle T2-weighted sequences on 3T. The visibility of the anatomy and image quality were comparable to a conventional coil and scored clinically acceptable by experienced radiologists. The novel coil displayed an increased SNR of 31% which could be exploited to accelerate the imaging protocols.
