Photograph of the eight-channel transmit/receive array (a). Representative flip angle map in the coronal plane (b). Coronal SNR maps (c) and SNR profiles in graphical format (d) were obtained at 3 T (4 element receive coil) and 7 T (8 element receive coil). There is 10-fold higher in the femoral neck and 5-fold higher at the superior hip joint space at 7 T compared to 3 T. The greater than expected linear SNR gains at 7 T are likely due to the use of more elements at 7 T.
