模拟ECG信号在320排CT冠脉成像中的应用价值

Application Value of Simulated ECG Signal in 320-slice CT Coronary Imaging

目的探讨模拟ECG信号在320排CT冠脉成像中的应用价值。方法收集和分析我院2015-01-01至2021-10-01期间,使用模拟ECG信号成像的20例患者(A组),与同时期,随机抽取的,常规技术成像的20例患者(B组)的冠脉成像结果,实行对照研究。结果A、B两组图像质量主观法评价,图像质量无显著差异(P=0.3758>0.05);A、B两组图像质量客观法评价,升主动脉根部,右冠状动脉近端,左前降支近端,左旋支近端CT值以及升主动脉根部层面噪声均无明显差异(P>0.05);A、B两组辐射剂量对比有显著差异(P<0.01)。结论模拟ECG信号在320排CT冠脉成像中的应用是可行的,值得推广。

Objective To explore the application value of simulated ECG signals in 320-slice CT coronary imaging.Methods Collect and analyze coronary artery imaging of 20 patients(group A)using simulated ECG signal imaging in our hospital from 2015-01-01 to 2021-10-01,At the same time,randomly selected,20 patients(group B)imaging with conventional techniques As a result,a controlled study was carried out.Results The image quality of the two groups A and B were evaluated subjectively,and the images were not significantly different(P=0.3758>0.05);the image quality of the two groups A and B was evaluated by objective methods,ascending aorta root,proximal right coronary artery,and left anterior There were no significant differences in CT values of proximal descending branch,proximal left circumflex branch,and ascending aortic root level noise(P>0.05);there was a significant difference in radiation dose between A and B groups(P<0.01).Conclusion Simulated ECG signal is feasible in 320-slice CT coronary imaging and is worthy of promotion.
