概要	Objective: Single-energy metal artefact reduction (SEMAR), a new technique that can now be used in routine CT examinations, has recently become applicable to volume data acquired with electrocardiography gating. We evaluated the effect of this technique on the visualization of the coronary arteries in patients harboring cardiac devices.Methods: We subjected 8 patients (7 males, 1 female; mean age 65.5 +/- 11.3 years)with implanted cardiac devices to coronary CT angiography on a 320-slice CT scanner (Aquilion ONE Vision (TM); Toshiba Medical Systems Corp., Tokyo, Japan). Image data sets were reconstructed with and without SEMAR. Two radiologists visually evaluated the image quality based on metal artefacts from the electronic device leads using a four-point scale (1=vessel not visible to 4=minimal or no metal artefacts). Images with a score of 3 or 4 were considered diagnostic.Results: In both SEMAR and non-SEMAR data sets, 94 coronary artery segments were available for evaluation. Without SEMAR, 11 segments (11.7%) were rated as non-diagnostic; SEMAR improved the image quality of 9 of the 11 segments (81.8%), and the images became diagnostic.Conclusion: SEMAR reduced metal arte
