The purpose of the study was to demonstrate the feasibility and evaluate the limitations of high-resolution MRI of ceramic implants in vivo. One healthy volunteer was subjected to high-resolution MRI before and after two zirconia dental implants were placed in the lower right jaw. Both implants were clearly depicted as signal voids, and no artifacts were observed using a turbo spin echo sequence. In conclusion, high-resolution in-vivo MRI of ceramic implants with an isotropic voxel size of (600 μm)3 is feasible within 5 minutes scan time.
