At present the duplex ultrasonic method is the best non-invasive examination method of the carotid and vertebrobasilar circulation. It was developed by a combination of the Doppler method with two-dimensional imaging in real time. It makes it possible to evaluate all stages of the stenotic process, the size and surface of plaques, the lumen of the vessels, occlusions. It provides a comprehensive picture of the morphology and function of vessels. The introduction of transcranial Doppler ultrasonography by R. Aaslid in 1982 made it possible to examine also basal intracranial arteries. Examination by ultrasound makes it possible to diagnose vascular changes in still asymptomatic patients; it helps to establish the correct diagnosis, offers the possibility to evaluate the therapeutic effect as well as terminal conditions-cerebral death.
目前，双功能超声检查法是颈及椎基底循环的最佳无创检查方法。它是由多普勒方法与实时二维成像相结合发展而来的。它能够评估狭窄过程的各个阶段、斑块的大小和表面情况、血管腔以及闭塞情况。它提供了血管形态和功能的全面图像。1982年R.阿斯利德引入经颅多普勒超声检查法，使得也能够检查颅内基底动脉。超声检查能够在患者仍无症状时诊断血管变化；有助于确立正确诊断，提供评估治疗效果以及终末期情况——脑死亡的可能性。
