摘要
目的:以DSA结果为金标准,评价64层螺旋CT血管造影对颈动脉狭窄的临床应用价值。方法:回顾性分析70例经DSA检查证实的颈动脉狭窄病人的CTA检查结果,以双侧颈动脉为观察对象,评价64层螺旋CT血管造影诊断颈动脉狭窄的准确性。结果:64层螺旋CT血管造影对颈动脉狭窄的诊断敏感度为96.5%,特异度为92.7%,阳性预测值为95.3%,阴性预测值为94.4%,准确度为95.0%。结论:64层螺旋CT血管造影对颈动脉狭窄的诊断具有重要的临床应用价值,是诊断颈动脉狭窄较理想的检查手段。
Objective：Compared with DSA results, to evaluate the clinical application of 64-slice spiral CT angiography in the diagnosis of carotid stenosis. Methods：Retrospectively analyse 70 cases with carotid arterious stenosis, which undergoing carotid CTA examination and DSA examination. Those patients＇ s bilateral carotid, which are abserved object to evaluate appreciate accuracy of 64-slice CTA in diagnosis of carotid arterious stenosis. Results：The sensitivity and specificity of 64- slice CTA in diagnosis carotid arterious stenosis is respectively 96.50%, 92.7%, positive predictive value is 95.30% , negative predictive value is 94.4% , degree accuracy is 95.5%. Conclusion 64-slice CT angiography have an important value for the diagnosis of carotid stenosis, and is an ideal examinational means for carotid stenosis.
