In elite sports, hamstring injuries are very common and show high recurrence rates. Diffusion tensor imaging is a promising technique to obtain detailed information like return to play time about the injury. Due to the requirement of long scan times and high signal to noise ratio (SNR), a 64-channel upper leg receive coil was developed and compared to a conventional coil in healthy volunteers. Both coils show similar B0 offset and variance. The upper leg coil showed an SNR increase of more than 45% in the biceps femoris long head muscle. This allows for further acceleration of the sequence.
