To compare the clinical detection rates in local lesions using the slice-encoding for metal artifact correction (SEMAC) & view angle tilting (VAT) Turbo Spin Echo (TSE) with the standard TSE sequence in patients with titanium screws. Following surgery, patients with reported discomfort at the operation site were examined with both TSE and SEMAC-VAT TSE imaging. They were also examined by digital radiography (DR) and computed tomography (CT). All images were assessed and scored. Despite the long scan time, SEMAC-VAT TSE reduced metal-induced artifacts and may improve the diagnostic sensitivity compared to standard TSE, DR and CT.
