Percentage change in signal-to-noise ratio (SNR) and percentage uniformity (U) values without and with the carbon fibre insert in place for the spin-echo (SE), turbo spin-echo (TSE) and gradient-echo (GE) sequences with the MultiTransmit switch (MX) turned “OFF” and then “ON”. The scanner's quadrature body coil configuration was used in this setup
