Study on the reduction of metal artifacts using the SEMAR technique

This retrospective study included 22 patients with dental metallic implants who underwent cervical spine computed tomography (CT) between January 6 and April 30, 2025. The SEMAR (Single Energy Metal Artifact Reduction) technique was applied to evaluate its effectiveness in reducing metal artifacts and image noise. The SEMAR-applied group demonstrated statistically significant improvements, with lower noise values, higher signal-to-noise ratios (SNR), and better qualitative image assessment scores (p < 0.05). These findings confirm that the application of the SEMAR technique not only reduces metal artifacts but also enhances SNR and diagnostic accuracy. Therefore, SEMAR can be considered a valuable tool for acquiring images with fewer metal artifacts, potentially contributing to its clinical application in various anatomical regions.
