摘　　要：目的探讨超微血流成像技术评价颈内动脉闭塞的价值。方法对23例多普勒彩超发现的可疑单侧颈内动脉闭塞患者分别行超微血流成像(SMI),超声造影以及数字减影血管造影(DSA)3种检查,比较SMI与DSA、超声造影与DSA,以及SMI与超声造影检查的一致性。结果 SMI显示颈内动脉完全闭塞15例,重度狭窄8例;超声造影显示颈内动脉完全闭塞13例,重度狭窄10例;DSA显示颈内动脉完全闭塞13例,重度狭窄10例。SMI与DSA、超声造影与DSA及SMI与超声造影的诊断一致性Kappa值分别为0.638、0.823、0.819。SMI与超声造影的诊断结果差异无统计学意义(P>0.05)。结论 SMI对颈内动脉闭塞有超声造影相似的价值。Objective To study the valuation of superb micro-vascular imaging （SMI） technology in assessing internal carot- id artery （ICA） occlusion. Methods Twenty-three patients with suspicious unilateral internal carotid artery occlusion discovered by colour doppler ultrasonography were chosen. Each patient has been examined by SMI, contrast-enhanced ultrasound （CEUS） and digital subtraction angiography （DSA）. The consistency between SMI and DSA,CEUS and DSA, SMI and CEUS were compared. Results SMI detected 15 completely occluded ICA and 8 severe stenosis. CEUS showed 13 completely occluded ICA and 10 severe stenosis. DSA explored 13 completely occluded ICA and 10 severe stenosis. The kappa value between SMI and DSA, CEUS and DSA,SMI and CEUS were 0. 638,0. 823,0. 819 respectively. There was no significant difference in diagnosising between SMI and CEUS （P〉0.05）. Conclusion SMI has the same diagnostic value as well as CEUS hut non-invasive examination. So it might be a new ultrasonic imaging technology in non-invasive evaluation of internal carotid artery occlusion.
