Doppler analysis of flow in intracranial arteries is now possible using a 2 MHz probe, allowing sufficient penetration of bone to obtain signals noninvasively and to measure rate of flow in middle (MCA), anterior (ACA) and posterior (PCA) cerebral arteries and in basilar trunk. Practical applications of this new method are numerous in cerebrovascular disease and, despite certain limitations due to anatomic factors, transcranial Doppler may identify stenosis of the intracranial arteries and study the value of collateral flow across the anterior circle of Willis in patients with extracranial carotid artery stenosis.
现在使用2兆赫探头可以对颅内动脉血流进行多普勒分析，该探头能充分穿透颅骨，以无创方式获取信号，并测量大脑中动脉（MCA）、大脑前动脉（ACA）、大脑后动脉（PCA）以及基底动脉主干的血流速度。这种新方法在脑血管疾病中有众多实际应用，尽管由于解剖因素存在一定局限性，但经颅多普勒检查仍可识别颅内动脉狭窄，并研究颅外颈动脉狭窄患者 Willis 环前交通支侧支循环的价值。
