T2-weighted MRI is essential to detect neural compression in the lumbar spine after spinal fusion surgery in patients with recurrent radicular symptoms. Unfortunately, off-resonance artifacts induced from lumbar fusion devices make the conventional T2-weighted MR images extremely challenging or impossible to interpret. We present a modified version of MAVRIC-SL, an MR sequence designed to correct for metal-induced artifacts, to allow T2 contrast, significantly improving diagnostic capabilities in the postoperative lumbar spine.
