Over the last decade, transcranial Doppler examination of the cerebral vessels has been made possible by the development of a high-intensity, low-frequency (2 MHz) pulse probe. The middle, the anterior and the posterior cerebral arteries, the cavernous portion of the carotid artery and the basilar artery can thus be easily studied transtemporally or transorbitally or from below the foramen magnum. The transcranial Doppler examination is already used clinically to study arteriosclerosis and in the diagnosis and follow-up of vasospasm and arteriovenous malformations. This review describes the examination procedure and summarizes and illustrates its major indications.
在过去十年中，高强度、低频率（2兆赫）脉冲探头的研制使经颅多普勒对脑血管的检查成为可能。由此可以很容易地经颞部、经眶部或枕骨大孔下方对大脑中动脉、大脑前动脉和大脑后动脉、颈动脉海绵窦段以及基底动脉进行研究。经颅多普勒检查已在临床上用于研究动脉硬化以及血管痉挛和动静脉畸形的诊断与随访。本文综述了该检查方法，并总结和阐述了其主要适应证。
