- W2385858845 abstract "Objective To evaluate the coronary artery stent imaging performance with HDCT in comparison with 64 slice CT.Methods 52 patients with 85 stents underwent CCTA using 64 slice CT and HDCT respectively.The CT values in stent lumen and the proximal unstented segments were measured.The diameters for these regions were also measured.Results There were significantly higher visibility ratio between the in stent and the proximal lumens with HDCT than that with the 64 slice CT(69.0% vs.42.9%;P0.01).The average CT value increased in stent lumen compared to the unstented segments,which was significantly increased with HDCT to 15.2 HU from the 54.2 HU with the 64 slice CT(P0.01).Conclusion With the improved spatial resolution and effective restrained from beam hardening artifact,HDCT improves the imaging clarity for coronary stents,and provides more accurate measurement for in stent lumen diameter compared to 64 slice CT." @default.
