(A) T1-weighted SEMAC-VAT image, of a 68-year-old female who underwent bilateral THA, showing irregularly shaped low intensity around the acetabulum (white arrow), which demonstrates bone resorption for lesions more than 2 mm wide. (B) T2-weighted TIRM SEMAC-VAT image, of a 68-year-old female who underwent bilateral THA, showing irregularly shaped low intensity around the acetabulum (white arrow), which demonstrates bone resorption for lesions more than 2 mm wide (C) The coronal T1-weighted SEMAC-VAT image, of a 68-year-old female who underwent bilateral THA, showing no positive signs. (D) The DR image, of a 68-year-old female who underwent bilateral THA, showing acetabular prosthesis dislocation (white triangle). DR = digital radiography; SEMAC-VAT = slice-encoding metal artifact correction and view-angle tilting; THA = total hip arthroplasty; TIRM = turbo inversion recovery magnitude.
