筛查颈动脉粥样硬化性病变多层螺旋CT血管造影和超声检查的价值分析

Value of Multislice CT Angiography and Ultrasonography in the Screening of Carotid Atherosclerotic Lesions

目的比较多层螺旋CT血管造影检查和超声诊断检查在动脉粥样硬化疾病中的诊断效果,阐明两种检查方法的临床应用价值和意义。方法方便选择该组于2015年1月—2016年12月期间收治的动脉粥样硬化老年患者100例,所有患者均先后进行超声检查和多层螺旋CT血管造影检查,比较两种检查方法的诊出率、诊断正确性、特异性和灵敏性,分析两种诊断方法的优缺点。结果两种诊断方法的诊出率、诊断正确性均较高,超声检查分别为92.57%和82.86%,血管造影检查分别为97.67%和88.0%;多层螺旋CT血管造影检查方法的特异性(84.57%)较超声检查(74.29%)更高,而灵敏性血管造影为74.29%则差于超声检查(80.0%)。结论超声检查和血管造影检查均具有较高的准确性,临床价值和应用意义重大,两种诊断方法各具优势,可在动脉粥样硬化疾病诊断中联合应用。

Objective This paper tries to compare the diagnostic value of multi-slice spiral CT angiography and ultrasonography in atherosclerotic disease and to clarify the clinical application value and significance of the two methods.Methods 100 old patients with atherosclerosis in the hospital from January 2015 to December 2016 were convenient enrolled in this study.All patients underwent ultrasonography and multi-slice spiral CT angiography.The two methods were compared.Diagnostic rate,diagnostic accuracy,specificity and sensitivity,and the advantages and disadvantages of the two diagnostic methods were analyzed.Results The diagnosis rate and diagnosis accuracy of the two diagnostic methods were higher,the sonographic examination was 92.57%and 82.86%respectively,and the angiographic examination was 97.67%and 88.0%respectively.The specificity of multi-slice spiral CT angiography was 84.57%,higher than that of ultrasonography(74.29%),whereas the sensitivity of angiography was 74.29%,which was worse than that of ultrasound(80.0%).Conclusion Ultrasonography and angiography have high accuracy,clinical value and application significance,the two diagnostic methods have their own advantages,can be used in the diagnosis of atherosclerotic disease combined.
