| 【】 目的 探究彩色多普勒超声(CDFI)与128排双源CT血管造影(DSCTA)在颈动脉狭窄病变(CAS)程度评价中的价值。方法 选择我院2014年10月至2017年3月期间收治的80例CAS患者,于1周内分别行CDFI和DSCTA检查,共296个血管节段,以DSA检查结果为“金标准”,对比分析CDFI和DSCTA的诊断结果。结果 以DSA检查结果为“金标准”,CDFI的灵敏度为87.88%,特异度为93.48%,符合率达90.95%,一致性Kappa=0.895,差异无统计学意义(P>0.05)；DSCTA的灵敏度为94.03%,特异度为97.50%,符合率达97.40%,一致性Kappa=0.916,差异无统计学意义(P>0.05)。结论 彩色多普勒超声(CDFI)与128排双源CT血管造影(DSCTA)均能准确地评估颈动脉狭窄病变程度,具有很好的一致性。CDFI因其快速简便无创可重复可作为筛查的首选方法,而DSCTA因费用、效率等问题不宜作为筛查手段,适合作为进一步明确诊断的检查方法。 |

| 【】Objective To assess the value of Color Doppler ultrasonography (CDFI) and 128-row dual source CT angiography (DSCTA) in the diagnosis of carotid artery stenosis. Methods 80 cases of carotid stenosis (CAS) including 296 segments in our hospital from October 2014 to March 2017 were selected, and examined by CDFI and DSCTA within one week. The results of CDFI and DSCTA were comparatively analyzed with the results of DSA as a golden. Results The sensitivity, specificity and coincidence rate of CDFI were 87.88%, 93.48% and 90.95% respectively with Kappa=0.895. The difference was not statistically significant (P>0.05). The sensitivity, specificity and coincidence rate of DSCTA were 94.03%, 97.50% and 97.40% respectively with Kappa=0.916. The difference was not statistically significant (P>0.05). Conclusion Color Doppler ultrasonography (CDFI) and 128-row dual source CT angiography (DSCTA) can accurately assess the extent of carotid stenosis with good consistency. CDFI can be used as the first choice for screening of CAS patients because of its rapid, simple, noninvasive and reproducible. DSCTA is not suitable for screening because of its cost and efficiency. It is suitable as a method of further definite diagnosis. |
