Metal-on-metal hip resurfacing implants are suitable for young, active patients. However, there are indications that these implants fail more frequently than traditional implants. An early diagnosis of prosthetic failure would be facilitated by artifact-reducing MRI protocols. The purpose of this study was to investigate to which extent metal artifacts can be reduced, in the worst case of a stainless steel implant, by optimizing routine imaging protocols. The result on a patient with hip joint implant showed that metal artifacts can be substantially reduced, thereby permitting anatomical details to be visualized closer to the implant.
