Abstract

Transcranial Doppler mapping, dual monitoring, color imaging, emboli detection, and insonation after administration of contrast media are recent technological advances that promise to bring new capabilities to transcranial Doppler ultrasonography, and are likely to change its applications in the near future. This article presents a critical review of these developments.

Role of transcranial Doppler ultrasonography in evaluation of patients with cerebrovascular disease.

Transcranial Doppler ultrasonography (TCD) is the only noninvasive examination method that enables the reliable evaluation of blood flow from the basal intracerebral vessels, adding physiologic information to the anatomic images. TCD is relatively inexpensive, can be performed at bedside, and allows monitoring in acute emergency settings and for prolonged periods with a high temporal resolution, making it ideal for studying dynamic cerebrovascular responses. In acute stroke, TCD is capable of providing rapid information about the hemodynamic status of the cerebral circulation and monitoring recanalization in real-time, with a potential for enhancing tissue plasminogen activator-induced thrombolysis. Extended applications such as emboli monitoring, right-to-left shunt detection, and vasomotor reactivity make TCD an important and valuable tool for evaluating stroke mechanisms, planning and monitoring treatment, and determining prognosis.
