双源CT冠脉成像对心肌桥诊断的优势及临床价值分析

Clinical value of dual source CT coronary angiography in the diagnosis of myocardial bridge

目的探讨双源CT诊断心肌桥的优势及临床价值。方法选取2015年1月~2016年4月我院放射影像科收治的169例心肌桥(MB)患者及31例行冠动脉造影及双源CT动脉成像检查的非MB患者作为研究对象,使用FLASH双源CT扫描仪及ARTIS数字减影造影机进行检查。结果双源CT冠脉检测MB的临床检出率为38.46%,高于对冠脉造影的检出率7.69%(P<0.05);双源CT冠脉检测共发现75处病灶,检出率为40.98%,高于冠脉造影检出率7.10%(P<0.05)。结论采用双源CT冠脉成像对MB患者进行检查便捷、无创且检出率较传统检查方法有显著提高。

Objective To explore the clinical value of CT and its clinical value in the diagnosis of myocardial bridge advantages. Methods One hundred and sixty nine MB patients were selected from January 2015 to April 2016 in the department of radiology in our hospital. Thirty one participants without MB were also enrolled in our study. All participants performed coronary artery angiography and dual source CT angiography examination, using the FLASH dual source CT scanner and ARTIS digital subtraction angiography. Results The clinical detection rate of dual source CT coronary to MB was 38.46%, which was significantly higher than that of coronary angiography of 7.69 %（P〈0.05）. Sev- enty five lesions were detected after dual source CT coronary artery examination, with the detection rate of 40.98%, which was significantly higher than that of coronary angiography of 7.10% positive rate （P〈0.05）. Conclusion The dual source CT coronary angiography is a more convenient and noninvasive examination method to MB disease detection than the traditional examination method with higher detection rate.
