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.
