目的：评价超声血管增强（VE）技术在颈动脉粥样硬化性狭窄（CAS）中的应用价值。方法 CAS患者70例，分别采用常规超声、彩色多普勒超声及VE技术检查颈动脉，测量颈动脉内径，计算狭窄率。结果70例患者超声共检出CAS轻度65条，中度43条，重度15条，完全闭塞1条。本组患者颈动脉狭窄处内径VE测值[（3.61±1.19）mm]与常规超声测值[（3.79±1.02）mm]和CDFI测值[（3.88±1.06）mm]比较差异有统计学意义（P＜0．05）。 VE技术评估颈动脉轻、中、重度狭窄的敏感性分别为86.5%、77.8%、85.0%，特异性分别为94.8%、96.3%、95.5%。结论 VE技术能清晰显示颈动脉管腔和管壁结构，提高超声诊断颈动脉狭窄程度的准确性，具有较高的临床应用价值。

Objective To explore the application of vascular enhancement(VE) technology in the diagnosis of carotid atherosclerotic stenosis(CAS). Methods Seventy patients with CAS were examined by two-dimension, CDFI and VE. The carotid artery diameter were measured and percentages of stenosis were calculated. Rusults Sixty-five arteries with mild CAS, 43 with moderate CAS, 15 with serve CAS and 1 with complete occlusion were detected among seventy patients.The differences of CAS measurements between VE and two-dimension,CDFI were significant (P<0.05). The sensitivity and specificity of VE technology for the evaluation of CAS were 86.5%,77.8%,85.0%and 94.8%,96.3%,95.5%. Conclusion VE technology can show lumen and wall more clearly,thus improving the accuracy of ultrasonography in the diagnosis of CAS degree with a great value in clinic application.
