We investigated the exchangeability of accelerated SEMAC TSE and high-bandwidth TSE MRI in patients with spinal hardware. Two musculoskeletal radiologists found through quantitative and qualitative evaluations of 50 patients with cervical, thoracic, and lumbar spinal instrumentation that accelerated SEMAC resulted in fewer metal artifacts, better visibility of anatomical structures and abnormalities, only mildly increased blur and similar soft tissue and bone contrasts. In the spine, accelerated SEMAC TSE can be used as a replacement, rather than “add-on”, of high-bandwidth TSE.
