【摘要】 目的 探讨64层螺旋CT对冠状动脉(冠脉)血管狭窄程度诊断的敏感性和特异性。方法 对同时进行冠脉64层螺旋CT检查和冠脉造影检查的60例患者的影像资料进行比对分析, 以冠脉造影检查结果作为冠心病诊断标准, 判定64层螺旋CT冠脉成像对冠脉血管狭窄程度诊断的敏感性和特异性。结果 本院60例患者分别开展64层螺旋CT冠脉成像和冠脉造影检查后, 截取清晰符合分析的血管图像。依次对患者的冠脉血管分别按左主干、前降支、回旋支和右冠共240支血管进行病情判定, 得出64层螺旋CT对冠心病诊断敏感性为90.0%、特异性为96.7%。结论 64层螺旋CT冠脉成像对于诊断冠脉血管病变具有较高的敏感性和特异性。

【Abstract】 Objective To investigate sensitivity and specificity of 64-slice spiral CT in diagnosis of coronary arterial stenosis. Methods A comparative analysis was made between imaging data of 64-slice spiral CT and coronary arteriography in 60 patients. Coronary arteriography outcome was taken as diagnostic criteria of coronary heart disease, and sensitivity and specificity of 64-slice spiral CT in diagnosis of coronary arterial stenosis were judged. Results Clear and standard vascular images were taken by 64-slice spiral CT and coronary angiogram for 60 patients in our hospital. Disease judgment was made on totally 240 left main coronary artery, anterior descending branch, circumflex artery and right coronary artery, and that showed sensitivity as 90.0% and specificity as 96.7% by 64-slice spiral CT in diagnosis of coronary heart disease. Conclusion 64-slice spiral CT contains high sensitivity and specificity in diagnosis of coronary vascular lesions.

伴随人们生活水平改善与饮食结构的变化, 冠心病的发病几率呈现出明显上升趋势, 逐渐成为影响国人健康状态的主要致病因素, 对此实现早期病变的诊断与治疗尤为重要。冠脉造影和冠脉血管CT成像是当前冠心病影像学检查的两种主要方法。介入技术的发展致使冠脉造影方法应用于临床治疗, 促使医生对冠心病实现更深一层次的认知, 该技术现已成为诊断冠心病的“金标准”, 依据造影结果可明确掌握冠状动脉的病变部位和程度。而现如今, 冠脉造影由于是一种有创检查手段导致患者顾虑进而限制该检测方法在临床诊治中的普及。64层螺旋CT通过对冠脉血管进行成像, 并且对于冠脉肌桥可从解剖上得以发现, 而且该检查方案具备快捷、无创和价格低廉等优点, 成为未来冠心病检测方法发展的趋势[1, 2]。……
