摘要: 本研究主要是探讨超微血流成像技术(SMI)诊断缺血性脑卒中患者颈动脉狭窄的应用价值。选取120例缺血性脑卒中者为研究对象,共178条病变血管,将DSA作为金标准,分析了常规血管超声和SMI检查对颈动脉狭窄的诊断准确性、特异性和敏感性。结果发现,常规血管超声和SMI检查的结果一致性较好(P<0.05);与常规血管超声相比,通过SMI诊断不同程度颈动脉狭窄的特异性与敏感性均有不同程度提高,尤其是针对中度和重度狭窄者,SMI诊断的准确性更好,且差异显著。总之,SMI技术可为临床提供一种新型的无创检查颈动脉狭窄的方法。

Abstract: This study is mainly to explore the application value of ultra-fine blood flow imaging technology (SMI) in the diagnosis of carotid artery stenosis in patients with ischemic stroke. 120 patients with ischemic stroke were selected as the subjects, including 178 arteries with stenosis. DSA is regarded as the gold standard, the accuracy, specificity and sensitivity of carotid artery stenosis by vascular ultrasound and SMI were analyzed. It was found that the vascular ultrasound and SMI achieved good consistency (P<0.05). Compared with vascular ultrasound, the specificity and sensitivity of carotid arteries by SMI were improved significantly, especially for moderate and severe stenosis, and the accuracy of SMI is better and the difference is significant. In conclusion, SMI technology can provide a new non-invasive method for carotid artery stenosis.
