　　[摘要] 目的 研究高频超声对糖尿病颈动脉血管粥样化（CAS）板块的诊断价值。方法 回顾性分析该院2014年1月―2016年1月收治的98例经DSA证实的CAS糖尿病患者的临床资料，所有患者均经高频超声检查。比较超声与DSA诊断结果，分析高频超声声像图特征。 结果 高频超声诊断轻、中度、重度狭窄及血管闭塞检出率与DSA结果比较差异无统计学意义（P>0.05），高频超声斑块检测率明显高于DSA（P http://

　　[Abstract] Objective This paper tries to study the diagnostic value of high frequency ultrasound in diabetic carotid artery atherosclerosis （CAS）. Methods The clinical data of 98 cases of CAS diabetes patients from January 2014 to January 2016 in this hospital tested by DSA were retrospectively analyzed； all patients were examined by high frequency ultrasonography. The diagnostic results of ultrasound and DSA respectively were compared， and the characteristics of high frequency ultrasound image were analyzed. Results There was no significant difference in the detection rate of mild， moderate， severe stenosis and vascular occlusion in high frequency ultrasonography and DSA（P>0.05）. The common carotid artery detection rate by ultrasonography was higher than that by DSA（P140 cm/s；闭塞：无血流信号。
