title: [Artifacts in MRT caused by instruments and implants].
abstract: Metallic instruments and implants can cause severe image artifacts in magnetic resonance imaging (MRI). Besides the properties of the materials and the geometrical arrangement of the devices, the applied MRI sequence type and its parameters (echo time, voxel size, read-out bandwidth, orientations of encoding directions, etc.) play also an important role. These interactions are presented in a systematic survey. A detailed description of the basic physical mechanisms underlying the generation of artifacts is also provided.
