Imaging techniques including transcranial Doppler (TCD), magnetic resonance imaging (MRI), computed tomography (CT), and cerebral angiography are available for cerebrovascular disease diagnosis. TCD is a less expensive, non-invasive, and practically simpler approach to diagnosing cerebrovascular disorders than the others. TCD is a commonly available and inexpensive diagnostic tool. However, owing to its large operator dependency, it has a narrow application area. Cerebrovascular disease indicates a group of disorders that alter the flow of blood in the brain. The brain's functions can be temporarily or permanently impaired as a result of this change in blood flow. Timely diagnosis and treatment can restore the brain-impaired functions, resulting in a much-improved prognosis for the patients. This review summarizes the basic principles underlying the TCD imaging technique and its utility as a diagnostic tool for cerebrovascular disease.
包括经颅多普勒（TCD）、磁共振成像（MRI）、计算机断层扫描（CT）和脑血管造影在内的成像技术可用于脑血管疾病的诊断。与其他方法相比，TCD是一种成本较低、非侵入性且实际操作更简单的诊断脑血管疾病的方法。TCD是一种常用且价格低廉的诊断工具。然而，由于其对操作人员的依赖性较大，其应用范围较窄。脑血管疾病是指一组改变大脑血流的疾病。由于这种血流变化，大脑功能可能会暂时或永久受损。及时的诊断和治疗可以恢复受损的大脑功能，从而使患者的预后得到显著改善。本综述总结了TCD成像技术的基本原理及其作为脑血管疾病诊断工具的效用。
