During MRI examination, implants made of various metal materials can cause serious artifacts in clinical examination, and the accuracy of disease diagnosis is reduced, wherein the artifacts are mainly represented by large low-signal areas at the metal implants or small high-signal areas at the edges and nearby of the metal implants, sometimes the high-signal areas extend backwards and upwards and the areas become smaller, so that adjacent tissues are also severely deformed and distorted; its generation has two reasons: firstly, the magnetic susceptibility of the metal implant is different from that of surrounding tissues, so that the local uniformity of a static magnetic field is destroyed, and the metal implant is a main cause of metal artifact; secondly, when the gradient coil is electrified to start and shut down, the metal implant generates induced current due to the change of the gradient field, which is also called vortex, and the linear relation between the proton nucleus and the gradient field is destroyed to cause irregular deformation of the image; with the increasing popularity of MRI devices, minimally invasive surgery such as tumor treatment with accurate positioning under MRI is becoming more and more mature. Therefore, research and development of novel medical metal materials and devices compatible with MRI has important clinical significance.
