目的:研究高清CT扫描及重建方式对冠状动脉支架图像质量的影响。方法:35例冠状动脉支架植入术后患者,共46枚支架,利用GE Discovery CT750 HDCT,采用高清扫描及重建方式成像。采用四级评分法对图像质量进行主观评分,数据分析采用SPSS16.0统计软件。结果:高清模式成像,冠状动脉支架显示清晰,对支架再狭窄能准确评估。结论:高清扫描及高清重建方式对冠状动脉植入支架显示较佳。
Objective: To study the effect of high-resolution CT scan and reconstruction on the coronary artery stent image quality. METHODS: Totally 35 stents were implanted in 35 patients undergoing coronary stent implantation using GE Discovery CT750 HDCT with HD scans and reconstructions. Subjective evaluation was made on the image quality by using the four-level score method. The data were analyzed by SPSS16.0 statistical software. Results: High-resolution imaging showed a clear coronary stent and accurate assessment of stent restenosis. Conclusion: High-resolution scanning and high-resolution reconstruction of coronary stent implantation shows better.
