The role of transcranial Doppler in detection of microembolic signals and evaluation of right to left shunts is also dealt with. Finally, its use in acute stroke is briefly outlined. In patients with stroke or transient ischemic attack of unclear etiology, especially in blacks, Orientals, or females, who have a higher incidence of intracranial arterial disease, TCD can be a very important noninvasive means for detecting stenosis of intracranial vessels. Diagnostic transcranial Doppler ultrasound (TCD) is commonly used in patients with acute stroke before or during treatment with intravenous thrombolysis (IVT). We aimed to assess how much TCD delays IVT initiation and whether TCD influences outcomes. The role of transcranial Doppler in detection of microembolic signals and evaluation of right to left shunts is also dealt with.

Transcranial Doppler screening is the only method to identify children and adolescents with sickle cell anemia who are at the highest risk of stroke, and its importance has recently been underscored by National Heart, Lung, and Blood Institute guidelines that strongly recommend children with sickle cell anemia receive an annual TCD screening.

Transcranial Doppler (TCD) is a diagnostic tool that can be used at bedside to assess the cerebral vasculature noninvasively. It is inexpensive, safe, and reliable when compared with other techniques. It can be repeated multiple times and can be used for continuous monitoring if needed. Screening of children with sickle cell disease to assess and prevent ischemic strokes and monitoring for Implantable transcranial Doppler. Sometimes a patient's history and clinical signs suggest a very high risk of stroke. Occlusive stroke causes permanent tissue damage over the following three hours (maybe even 4.5 hours), but not instantly.

The technology failed to meet its vision due to the difficulty in locating Transcranial Doppler ultrasound (TCD) was used to evaluate the possibilities of hypoperfusion, hyperperfusion, and embolization as causes of stroke and to evaluate the significance of Doppler microembolic signals (DMES).
