The　study　aimed　for　evaluating　the　diagnostic　value　of　a　2D　Turbo　Spin　Echo　(TSE)　magnetic　resonance　(MR)　imaging　sequence　implanted　slice-encoding　metal　artifact　correction　(SEMAC)　and　view-angle　tilting　(VAT)　in　patients　with　spinal　instrumentation.　Sixty-seven　consecutive　patients　with　an　average　age　of　59.717.8　years　old　(range:　32-75　years)　were　enrolled　in　this　study.　Both　sagittal,　axial　T1-weighted　and　T2-weighted　MRI　images　were　acquired　with　a　standard　TSE　sequence　and　a　high-bandwidth　TSE　sequence　implemented　the　SEMAC　and　VAT　techniques.　Three　continuous　sections　around　the　instrumentation　in　axial　and　sagittal　images　were　selected　for　quantitative　evaluation.　The　measurement　included　cumulative　areas　of　signal　void　on　axial　images　and　the　length　of　spinal　canal　obscuration　on　sagittal　images.　Three　radiologists　independently　evaluated　all　images　blindly.　The　inter-observer　reliability　was　evaluated　with　inter-class　coefficient.　We　defined　patients　with　discomfortable　symptoms　caused　by　spinal　instrumentation　as　spinal　instrumentation　adverse　reaction.　Visualizations　of　all　periprosthetic　anatomic　structures　were　significantly　better　for　SEMAC-VAT　compared　with　standard　imaging.　For　axial　images,　the　area　of　signal　void　at　the　level　of　the　instrumentation　were　statistically　reduced　with　SEMAC-VAT　TSE　sequences　than　with　standard　TSE　sequences　for　T2-weighted　images　(9.9　+/-　2.6cm(2)　vs　29.8　+/-　14.7cm(2),　P＜0.001).　For　sagittal　imaging,　the　length　of　spinal　canal　obscuration　at　the　level　of　the　instrumentation　was　reduced　from　5.2　+/-　2.0cm　to　1.2　+/-　0.6cm　on　T2-weighted　images　(P＜0.001),　and　from　4.8　+/-　2.1cm　to　1.1　+/-　0.5cm　on　T1-weighted　images　with　SEMAC-VAT　sequences　(P＜0.001).　Interobserver　agreement　for　visualization　of　anatomic　structures　and　image　quality　was　good　for　both　SEMAC-VAT　(k=0.77　and　0.68,　respectively)　and　standard　(k=0.74　and　0.80,　respectively)　imaging.　The　number　of　abnormal　findings　noted　on　SEMAC　images　(59　findings)　was　significantly　higher　than　detected　on　standard　images　(40　findings).　The　incidence　rate　of　spinal　instrumentation　adverse　reaction　was　38.81%.　MR　images　with　SEMAC-VAT　can　significantly　reduce　metal　artifacts　for　spinal　instrumentation　and　improve　delineation　of　the　instrumentation　and　periprosthetic　region.　Furthermore,　SEMAC-VAT　technique　can　improve　diagnostic　accuracy　in　patients　with　post-instrumentation　spinal　diseases.
