Significant
in-plane and through-plane 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. Volunteers with joint replacements (hip, shoulder, or
knee) were scanned using a 2D FSE sequence optimized for imaging around arthroplasty
and a MAVRIC sequence. MAVRIC scans were effective in reducing the metal
susceptibility artifact for all joints and also better highlighted the extent of osteolysis.
Higher resolution FSE images were effective for detection of formation of
fibrous membrane around arthroplasties. This study further supports the use
of MAVRIC for clinical implementation.
