MAVRIC SL, a multi-spectral MRI imaging sequence, reduces metallic susceptibility artifact to improve visualization near joint arthroplasty by acquiring 24 spectral bins of off-resonance data. Many implants require fewer bins, and this study uses a calibration scan to determine the number of bins necessary to permit an isotropic MAVRIC acquisition and a reduced TR isotropic MAVRIC acquisition. The isotropic MAVRIC images decreased blurring and improved visualization of the periprosthetic bone and synovium while retaining image quality. Lowering the TR decreased scan time but affected image interpretation. Isotropic MAVRIC acquisitions may improve the diagnostic capability of MAVRIC SL images.
