Improved metal reduction techniques for conventional MRI pulse sequences and the addition of MAVRIC (multiacquisition variable resonance image combination) have been established as useful in assessing component osteolysis and synovial reactions. The purpose of this retrospective study was to determine the utility of MRI in assessing loosening of total hip arthroplasty in a cohort of patients using surgical confirmation of loosening as the gold standard. Our results show that loosening can be predicted with high sensitivity and specificity; however, intraoperative variability in assessing loosening and the overall low frequency of implant loosening are limiting factors.
