Fig. 3.
The SNR distribution at b = 2000 s/mm2 in one volunteer for the different coils and imaging protocols, where voxels in the blue spectrum exhibits an SNR < 3 and will suffer from signal bias due to the rectified noise floor. The RT-coil SNR maps exhibit low values in the mid-sagittal plane due to the placement and design of the flex coils. Multiband acceleration (SMS) reduced the overall SNR for the RT-coil setup and caused severe distortions in the anterior parts of the image.
