64层螺旋CT冠状动脉CTA动态容积再现图像辅助诊断心肌桥的临床应用价值

The Clinical Value of 64-slice CT Coronary CTA Dynamic Volume Rendering Image in the Diagnosis of Myocardial Bridge

目的探讨运用64层螺旋CT冠状动脉CTA动脉容积再现图像辅助诊断心肌桥的临床效果。方法选取我院的自2011年7月26日至2012年6月29日期间行冠脉CTA检查并诊断为心肌桥的患者10例,观察其动态容积再现图像,诊断结果,并做统计学分析和处理。结果 1059例患者中,静态CTA图像诊断心肌桥6例,静态和动态图像共同诊断心肌桥9例。敏感度分别是80.34%和92.78%,特异度分别是99.47%和99.78%,统计学上有意义(p<0.05)。结论运用64层螺旋CT冠状动脉CTA动态容积再现图像进行辅助诊断心肌桥,具有较好的临床效果,值得在临床上广泛推广和应用。

Objecdve To investigate the clinical value of 64-slice CT coronary, CTA dynanfic volume rendering image in the diagnosis of myocardial bridg. Methods 10 patients who unclerwent coronary CTA from July 26, 2011 to June 29, 2（112 and diagnosed with myocardial bridge were collected. The dynamic vohlme rendering images and diagnostic results were statistically analyzed and processed. Results Of all 1059 cases, 6 cases were diagnosed with myocardial bridge by static CTA images, and 9 cases were diagnosed with myocardial bridge by static CTA images combined with dynamic images. The sensitivity was 80.34% and 92.78% respectively, and the specificity was 99.47% and 99.78% respectively, it was statistically significant （p〈0.05）. Conclusion The application of 64-slice CT coronary, CTA dynamic volume rendering image on the diagnosis of myocardial bridge has important clinical significance and is worth spreading widely in clinics.
