Core Tip	Single-energy metal artifact reduction (SEMAR) is a computed tomography (CT) algorithm designed to reduce metal-induced artifacts while preserving vessel contrast. In this retrospective single-center study, lower limb CT angiography examinations in 22 patients with metallic fixation prostheses were reconstructed with and without SEMAR to assess arterial signal-to-noise ratio, contrast-to-noise ratio, artifact burden, and diagnostic confidence. SEMAR significantly reduced metal artifacts, improved signal-to-noise ratio and overall image quality, and restored periprosthetic arterial visualization to levels comparable with the contralateral reference limb, without compromising vascular contrast, thereby enhancing the diagnostic performance of lower limb CT angiography in this challenging patient population.
