Zochowski KC, Miranda MA, Cheung J, et al. - Ninety-three hip arthroplasties (85 total hip replacements and eight hip resurfacings [nine bilateral hips]) in 84 patients were imaged and assessed by the researchers in order to contrast the quality and diagnostic utility of the three metal artifact reduction sequences in assessing hip arthroplasties, ie, conventional multiacquisition variable-resonance image combination selective (MAVRIC SL), isotropic MAVRIC SL, and reduced-TR isotropic MAVRIC SL. Calibration scans reduced the number of bins required. Isotropic MAVRIC SL acquisitions had the most extended scanning time, and conventional and reduced-TR isotropic MAVRIC SL acquisitions had scanning times that were comparable. In comparison with conventional MAVRIC SL images, both isotropic and reduced-TR isotropic MAVRIC SL images exhibited diminished blurring and enhanced visualization of the synovium and periprosthetic bone. Isotropic MAVRIC SL acquisitions more efficiently enhanced signal-to-noise ratio (SNR), visualization of the synovium and periprosthetic bone, and lesion conspicuity and reduced blurring in contrast with reduced-TR isotropic MAVRIC SL acquisitions. In conclusion, isotropic MAVRIC SL acquisitions enhance SNR, conspicuity of lesions, and visualization of synovium and periprosthetic bone and reduce blurring in comparison with conventional MAVRIC SL acquisitions.
