| 摘 要： | 目的: 探讨64层螺旋CT冠状动脉成像（MSCTCA）判定冠状动脉狭窄的临床价值。方法: 回顾性研究在我科治疗并于2周内先后行MSCTCA和冠状动脉造影（CAG）的临床拟诊冠心病患者30(男21，女9)例；年龄49～74（62±7）岁，以CAG结果为准，计算评价指标。结果: 依节段计算的MSCTCA准确性，其灵敏度、特异度分别为50%、97%。若去除38个冠脉节段由于严重钙化而影响诊断的因素，则其灵敏度、特异度分别为74%、99%。结论: MSCTCA判断冠状动脉中、重度狭窄具有较高的准确性，对诊断冠心病尤其对筛选冠心病而言有较好的前景，但严重钙化病变影响冠状动脉狭窄程度的判断。

| Abstract: | AIM: To compare the accuracy and limitations of 64-slice CT (MSCT) coronary angiography with invasive coronary angiography in the detection of significant coronary stenosis (≥50% lumen diameter narrowing). METHODS: Data were from 30 subjects ［21 males, 9 females, mean age (62±7) years, range: 49-74 years］ who had undergone MSCT and invasive coronary angiography within 2 weeks. Two experienced cardiologists analyzed the images of MSCT and invasive coronary angiography. RESULTS: For accuracy of coronary MSCT by each lesion segment, the average sensitivity was 50% and the average specificity 97%. Excluding the effect of 38 coronary segments with severe calcification, sensitivity and the specificity of MSCT were 74% and 99%, respectively. CONCLUSION: MSCT coronary angiography has a high accuracy rate and good potential for detection of coronary stenosis. However, severe calcification affects the accuracy in the detection of stenosis. |
