摘　　要：目的探讨腔内凸阵超声探头体外途径检查颈动脉的应用价值。方法选取43例患者86支颈动脉作为研究对象,用高频线阵探头、低频凸阵探头及腔内凸阵探头分别检测颈总动脉(CCA)内径、收缩期峰值流速(PSV),颈内动脉(ICA)内径、PSV、异常血管形态及显示长度等参数并进行比较。结果3种不同频率超声探头所测ICA内径、PSV、显示长度比较具有显著性差异;ICA异常形态血管比较,腔内探头与高频探头之间有统计学差异。结论腔内凸阵探头检测ICA具有较高的临床应用价值。Objective To assess the value of an intracavitary convex array probe in detecting internal carotid artery (ICA) disease. Methods Eighty-six carotid arteries in 43 cases were examined with intracavitary convex array probe, low-frequency convex array probe and high-frequency linear probe to collect the data including the ICA visible length, peak systolic velocity (PSV), internal diameter, blood vessel shape; common carotid artery (CCA) intimae-medial thickness (IMT), PSV, and internal diameter. Results Signif...
