16层螺旋CT对下肢动脉闭塞性疾病的诊断运用探究

目的:研究16层螺旋CT对下肢动脉闭塞性疾病的诊断运用。方法:选择40例下肢动脉闭塞性疾病患者进行研究,分别采用16层螺旋CT(CTA),并在检查2周后,采用临床作为金标准的数字减影血管造影(DSA)手段进行诊断。检查后,分别比较两种诊断手段的敏感性、特异性和准确性。并对两种诊断方式对下肢动脉闭塞疾病诊断对狭窄分级情况的比较分析。结果:检查后,发现CTA组与DSA组诊断的敏感性、特异性和准确率差异均无统计学意义(P>0.05);两种方法诊断的狭窄程度的1～5级的分级情况差异无统计学意义(P>0.05)。结论:采用16层螺旋CT对下肢动脉闭塞性疾病进行诊断,效果良好,值得临床推广应用。

Application of 16-slice Spiral CT in Lower Extremity Arterial Occlusive Diseases

Objective To study the diagnosis of 16 slice spiral CT in lower extremity arterial occlusive disease by.Methods 40 cases of lower extremity arterial occlusive disease were studied,using 16 slice spiral CT(CTA),and in the 2 weeks after the inspection,the clinical gold standard for digital subtraction angiography(DSA) diagnosis.After inspection,to compare the two kind of diagnosis sensitivity,specificity and accuracy.And the two kinds of diagnosis methods on the lower extremity arterial occlusive disease diagnosis of stenosis of the comparative analysis.Results After inspection,found in the CTA group and DSA group diagnosis sensitivity,specificity and accuracy rate showed no significant difference(P> 0.05);two stenosis degree method in the diagnosis of the 1-grade 5 class differences had no statistical significance(P>0.05).Conclusion Using 16 slice spiral CT in lower extremity arterial occlusive disease diagnosis,good effect,worthy of clinical application.
