目的探讨64层螺旋CT对冠状动脉狭窄病变诊断的准确性。方法选取2013年12月—2015年12月心血管内科收治的冠状动脉疾病和疑似冠心病的患者100例,对所有患者均进行64排螺旋CT冠状动脉成像和选择性冠状动脉造影,前后时间不超过2周,以选择性冠状动脉造影的检测结果为准,分析对比冠状动脉中度及中度以上狭窄的患者应用64排螺旋CT进行诊断的结果。结果与选择性冠状动脉造影相比应用64排螺旋CT进行诊断冠状动脉轻、中、重度以上狭窄的准确度较高,64排螺旋CT显示冠状动脉中度及中度以上狭窄的精确值、阳性率、钙化病变、精确值和阳性率分别为91.00%、66.00%、86.00%、59.00%。结论诊断冠状动脉管腔狭窄采用64排螺旋进行在临床上的应用价值显著,特别是对中度及中度以上的管腔缩小的检测有着较高的敏感性,64排螺旋作为一种无创性检查,能够对疾病做出早期诊断且定位准确,可广泛应用于冠状动脉狭窄的临床诊断。
Objective To investigate the accuracy of 64-slice spiral CT in the diagnosis of coronary artery stenosis. Methods 100 patients with coronary artery disease and suspected coronary heart disease admitted from December 2013 to December 2015 in our department were enrolled. All patients underwent 64-slice spiral CT coronary angiography and selective coronary angiography before and after For more than 2 weeks, the results of selective coronary angiography prevail and analyze the results of 64-slice spiral CT in patients with moderate and severe coronary arteries. Results Compared with selective coronary angiography, the accuracy of 64-slice spiral CT in the diagnosis of mild, moderate and severe coronary stenosis was high. The accuracy of 64-slice spiral CT in detecting moderate and moderate coronary stenosis was higher than that of selective coronary angiography Rate, calcified lesions, the exact value and the positive rate were 91.00%, 66.00%, 86.00%, 59.00%. Conclusion The diagnosis of coronary stenosis with 64-row spiral in the clinical application of significant value, especially for the detection of moderate and moderate lumens have a higher sensitivity, 64-row spiral as a noninvasive Check, to make early diagnosis of disease and accurate positioning can be widely used in the clinical diagnosis of coronary artery stenosis.
