There has been an increasing interest to acquire high-resolution diffusion MRI at ultrahigh field (≥7 Tesla) due to the increased SNR and improved parallel imaging performance. To fully capitalize on the benefit of ultrahigh field, it is desirable to image with many receiver coils. In this study, we acquired slice-accelerated whole-brain 1.05-mm isotropic diffusion images on an FDA-approved 7 Tesla scanner (Siemens Terra) using a homemade 63-channel head RF array with various slice and in-plane accelerations. We found that the use of 63 channels can achieve higher acceleration factors (up to 9-fold acceleration in total) while maintaining the image quality.
