To evaluate the typical appearance and the influence in the image interpretation of the metallic artifact which is known as one of the patient-related field artifacts, we anaysed the magnetic resonance (MR) images of 40 patients (the total number of metallic materials were surgical wires and clips, orthopedic devices, and the other miscellaneous materials. The artifacts properties, metallic implants were surgical wires and clips, orthopedic devices, and the other miscellaneous materials. The artifacts produced by metallic object can be seen on MRI as the focal loss of signal and/or the local distortion of the image. Regardless of their ferromagnetic properties, metallic, such as a lead fragment showed wevere artifacts and nonferromagnetic metals showed mild to moderate arifacts. The conspicuity of artifact was related to the composition, mass, shape, orientation, and the location of the metallic objects in the body. Under high magnetic field strength, there were no significant differences between the various pulse sequences. Artifacts are particularly prominent on gradient -echo images. Our findings indicate that MR imaging of patients with standard nonferromagnetic metallic materials can be successfully performed and usefully interpreated.
