The purpose of this study is to evaluated the appropriate combination of elements out of 32 coil elements to obtain the high-resolution image without phase wrap-around artifact using 3T MR scanner with 32-channel head coil and small FOV setting. Each coil element images are reconstructed and combined into the final image by sum of square method. Visual inspection of each coil element images for phase wrap-around artifact was used. With this method, we can obtain small FOV high-resolution T2-weighted images without phase wrap-around artifact. This method may help clinical application of 3 T MR with 32-channel head coil.
