摘　　要：探讨颈动脉粥样硬化斑块患者采用超声超微血管成像(SMI)技术检测斑块内新生血管形成的临床价值。选取经彩色多普勒颈动脉超声检查确诊的100例颈动脉粥样硬化患者作为研究对象,所有纳入对象均接受SMI、超声造影(CEUS)检查,以CEUS检查结果作为判断标准,计算SMI检测结果与CEUS结果的一致性。颈动脉彩色多普勒超声检出低回声斑块的平均厚度为(3.22±1.07)mm,平均斑块长度为(11.60±3.31)mm;混合回声斑块的平均厚度为(3.50±1.21)mm,平均斑块长度为(17.32±4.16)mm;SMI技术检出分级与CEUS分级的一致性kappa值为0.516,P=0.000;Spearman R=0.704,P=0.000;SMI技术检出分级与CEUS分级具有较高的一致性和相关性。SMI技术检测颈动脉粥样硬化斑块内新生血管形成与CEUS结果具有较高的一致性和相关性,可以作为一种无创、快速、方便的检测手段应用于临床。This study explored the clinical value of superb microvascular imaging(SMI)in detecting neovascularization in carotid atherosclerotic plaque.A total of 100 patients with carotid atherosclerosis diagnosed by color Doppler carotid ultrasound were selected as the research objects.All the included subjects were examined by SMI and contrast-enhanced ultrasound(CEUS).The results of CEUS were used as the criteria to calculate the consistency between SMI test results and CEUS results.The average thickness of hypoechoic plaques detected by carotid color Doppler ultrasound was(3.22±1.07)mm,the average patch length was(11.60±3.31)mm;the average thickness of mixed echo plaques was(3.50±1.21)mm,the average patch length was(17.32±4.16)mm,the consistency kappa value between SMI detection grading and CEUS grading was 0.516,P=0.000,Spearman R=0.704,P=0.000,SMI and CEUS had high consistency and correlation.SMI has high consistency and correlation with CEUS results in detecting neovascularization in carotid atherosclerotic plaques,which can be used as a noninvasive,rapid and convenient detection method.
