Effective imaging evaluation after joint replacement is important for patients with malignant bone tumor. This study investigated the diagnostic value of MR imaging with metal artifact reduction sequences (MARS) in local recurrence of malignant bone tumor after joint replacement. The sensitivity, specificity, coincidence rate and Kappa value of MARS in the diagnosis of local recurrence were higher than FSE sequences. The ICC was 0.961 between MR images and pathology in measuring recurrent tumor volume. MR imaging with MARS has significant diagnostic value in local recurrence of malignant bone tumor after joint replacement.
