Abstract
A mathematical model of dual-component paramagnetic and diamagnetic ma terial to cancel metal-induced MRI artifacts was developed and verifie d experimentally. The magnetization produced by metallic material and then the gradient linearity distortion can be cancelled by using such materials with opposing paramagnetic and diamagnetic properties. This concept of dual-component materials provides a novel solution to the p roblem of MRI artifacts.
