Magnetization-prepared rapid acquisition with gradient-echo (MPRAGE) images of 25-year-old healthy female participant.

Caption

A-C, MPRAGE images obtained with 8-channel (A), 16-channel AIR (B), and 32-channel (C) head coils. Surface coil intensity correction has been applied for these images via vendor-provided algorithm. Nonspecific white matter lesions and perivascular spaces (white arrow) evaluated for scoring of structural sharpness were better depicted on 32-channel relative to 16-channel AIR and on 16-channel relative to 8-channel coil. Frontal signal loss of 16-channel AIR coil is shown by red arrow in B. AIR coil element placement in this prototype was not specifically optimized for uniformity, and this may be improved in future designs.
