摘要
目的分析多层螺旋CT冠状动脉血管成像技术临床应用价值,总结应用经验。方法方便选取2015年1月—2017年2月福州总院九五医院临床部放射科医院共开展冠脉螺旋CT冠状动脉血管成像294例次。评价成像质量、冠脉血管段显示率,各类心脏并显示情况。对比CT评估高风险以及低风险对象最终手术治疗或出现心脏不良事件率。结果成像质量满意率100.00%,冠脉血管段显示89.41%(3 943/15×294)。诊断冠心病、心肌桥、左心功能不良、先天冠脉血管发育异常等疾病,冠脉血管造影与CT诊断符合率为100.00%(24/24)。CT评估高风险患者采用手术治疗或出现心脏不良事件率高于低风险对象,差异有统计学意义(P<0.05)。CT检查期间,出现不良反应2例。结论多层螺旋CT冠状动脉血管成像技术可用于疾病诊断、风险预测、治疗方式和选择指导、疗效评价等,但也存在不良反应,对部分冠脉段显示不清。
Objective This paper tries to analyze the multi-slice spiral CT coronary angiography technique and its clinical application value and to summarize the clinical experience. Methods From January 2015 to February 2017, 294 cases of CT coronary artery angiography were carried out. The imaging quality, coronary artery segment display rate, various types of heart disease were convenient selected. The adverse events rate of heart disease diagnosed by CT of high risk subjects and low risk subjects was compared. Results The satisfaction rate of the imaging quality was 100.00%, coronary vascular segments display accounted for 89.41%（3 943/15×294）. In the diagnosis of coronary heart disease, myocardial bridge, left ventricular dysfunction, congenital coronary vascular development abnormality, the coincidence rate of coronary angiography and CT diagnosis was 100.00%（24/24）. CT assessment of high risk patients with surgery or adverse cardiac events was higher than that of low risk subjects, the difference was statistically significant（P〈0.05）. During the CT examination, 2 cases had adverse reactions. Conclusion Multi-slice spiral CT coronary angiography technology can be used in disease diagnosis,risk prediction, treatment and selection of guidance, evaluation of curative effect, but there are also some bad reactions,such as unclear display of part of coronary section.
