Reducing or resolving susceptibility artifacts is important for development of materials for medical implants. In this study, we measured and evaluated magnetic susceptibility artifacts for various metals and ceramics using two MRI systems with different static magnetic field strengths and multiple imaging sequences. MR images were acquired following the criteria of the spin echo sequence and gradient echo sequence required in the US FDA standard artifact evaluation test. The results were used to clarify the relationships among artifact size in MR images, volume magnetic susceptibility of samples, and static magnetic field strength of the MRI system.
