目的:探讨多层螺旋计算机断层扫描(CT)冠状动脉造影的扫描技术特点及价值;方法:选取2015年1月至2016年6月广州医科大学附属第三医院收治的冠心病患者74例,对其进行多层螺旋CT冠状动脉造影检查,分析检查结果。结果:抗胰岛细胞抗体(ICA)血管直径超过2 mm的共计724段,其中,满足影像学评价的共计672段(92.82%),不满足影像学评价的共计52段(7.18%)。经ICA检查显示,74例患者中,轻度狭窄42支,占56.8%;中度狭窄31支,占41.9%;重度狭窄37支,占50.0%;多层螺旋CT检查结果显示,74例患者中,轻度狭窄41支,占55.4%;中度狭窄31支,41.9%;重度狭窄38支占51.4%,两种检查结果差异无统计学意义(P>0.05)。结论:多层螺旋CT冠状动脉成像是一种新型的检查方法,具有快速、无创的特点,在CT图像可以满足诊断需求的情况下,多层螺旋CT对冠状动脉狭窄的诊断有着较高的特异度、敏感度,有利于冠心病的前期诊断。
Objective: To explore the characteristics and value of scanning technique of multi-slice spiral computed tomography (CT) coronary angiography. Methods: From January 2015 to June 2016, 74 patients with coronary heart disease admitted to the Third Affiliated Hospital of Guangzhou Medical University The multi-slice spiral CT coronary angiography, analysis of test results. Results: A total of 724 segments with anti-islet cell antibody (ICA) diameter of more than 2 mm were included, of which 672 segments (92.82%) satisfied the imaging evaluation and 52 segments (7.18%) did not meet the imaging evaluation. According to ICA examination, 42 of 74 patients were mild stenosis (56.8%), 31 were moderate stenosis (41.9%), 37 were severe stenosis (50.0%). Multi-slice spiral CT showed that 74 patients There were 41 mild stenoses (55.4%), 31 moderate stenoses (41.9%), and 38 severe stenoses (51.4%). There was no significant difference between the two test results (P> 0.05). Conclusion: Multislice spiral CT coronary angiography is a new type of examination method with fast and noninvasive characteristics. MSCT has a high specificity for the diagnosis of coronary artery stenosis when the CT images can meet the diagnostic needs Degree, sensitivity, is conducive to the pre-diagnosis of coronary heart disease.
