Significant susceptibility artifacts occur when performing MRI around orthopedic hardware. This study evaluated standard of care 2D FSE imaging with the multi-acquisition variable-resonance image combination (MAVRIC) technique. Patients with joint replacements (hip or shoulder) were scanned using optimized 2D FSE and MAVRIC sequences. MAVRIC scans improved the visualization of the synovium, bone and supraspinatus tendon in the shoulder. MAVRIC scans resulted in increased detection of synovitis, peri-prosthetic osteolysis and supraspinatus tendon tears, resulting in a change in diagnosis almost 50% of the cases. This study further supports the use of MAVRIC for clinical implementation.
