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.
