Transcranial Doppler (TCD) ultrasonography is a rapid, noninvasive, real-time, and low-cost imaging technique. It is performed with a low-frequency (2 MHz) probe in order to evaluate the cerebral blood flow (CBF) and its pathological alterations, through specific acoustic windows. In the recent years, TCD use has been expanded across many clinical settings. Actually, the most widespread indication for TCD exam is represented by the diagnosis of paradoxical embolism, due to patent foramen ovale, in young patients with cryptogenic stroke. In addition, TCD has also found useful applications in neurological care setting, including the following: cerebral vasospasm following acute subarachnoid hemorrhage, brain trauma, cerebrovascular atherosclerosis, and evaluation of CBF and cerebral autoregulation after an ischemic stroke event. The present review aimed to describe the most recent evidences of TCD utilization from neurological to cardiological setting.
经颅多普勒超声（TCD）是一种快速、无创、实时和低成本的成像技术。它使用低频（2MHz）探头通过特定的声窗来评估脑血流（CBF）及其病理变化。近年来，TCD 的应用已扩展到许多临床环境中。实际上，TCD 检查最广泛的适应证是诊断卵圆孔未闭引起的年轻隐源性卒中患者的反常栓塞。此外，TCD 在神经科护理环境中也有一定的应用，包括以下方面：急性蛛网膜下腔出血后的脑血管痉挛、脑外伤、脑血管粥样硬化以及缺血性卒中后 CBF 和脑自动调节的评估。本综述旨在描述 TCD 在从神经科到心内科的应用的最新证据。
