A 16-channel head coil using novel Adaptive Image Receive (AIR) technology was compared to 8-channel and 32-channel head coils on the Compact 3T system in nine healthy subjects using MPRAGE, FLAIR, GRE, and T2 FSE pulse sequences. Two neuroradiologists graded the AIR coil against the 8-channel and 32-channel coils on signal-to-noise ratio, gray-white matter contrast, lesion depiction, artifact, and overall image quality. On average the AIR coil performed similar to the 8-channel head coil, though not as well as the 32-channel coil. This study demonstrates feasibility of AIR coil technology for imaging of the brain and denotes areas on which future coil designs may improve.
