Abstract: A theoretical mathematical model of dual component paramagnetic and diamagnetic material to cancel metal-induced magnetic resonance imaging (MRI)artifacts was investigated and evaluated. The magnetization produced by material causes gradient linearity distortion. By using materials with opposing paramagnetic and diamagnetic properties it is supposed to compensate these effects. Therefore the interferences by paramagnetic and diamagnetic materials on Images in a closed 1.5 Tesla high field magnetic resonance imaging System were experimentally examined for different types of sequences and correlated to their magnetic susceptibility. Basing on this results the concept of dual-component materials to solve the problems of MRI-artifacts was theoretically checked by using the finite element method and experimentally in the MRI.
