Principles of Transcranial Doppler Ultrasonography
2020Transcranial Doppler (TCD) ultrasonography is a non-invasive bedside tool applied to the assessment of cerebral blood flow haemodynamics in major intracranial arteries. TCD allows dynamic monitoring of vessel pulsatility, with a high temporal resolution, and it is relatively inexpensive, repeatable and portable.

Role of Transcranial Doppler Ultrasonography in Cerebrovascular Disease
Recent Patents on CNS Drug Discovery, 2010Transcranial Doppler ultrasonography (TCD) is the only non-invasive examination that provides a reliable evaluation of intracranial blood flow patterns in real-time, adding physiological information to the anatomical information obtained from other neuroimaging modalities. TCD is relatively cheap, can be performed bedside, and allows monitoring both in

Transcranial colour Doppler ultrasonography
Rivista di Neuroradiologia, 2001Transcranial colour Doppler ultrasonography (TCCD), being a non-invasive method is an invaluable source of information on cerebral haemodynamics. It is the blood flow disturbances that often lead to irreversible ischemic lesions, which can then be detected a posteriori with various imaging techniques.

Vascular Dizziness and Transcranial Doppler Ultrasonography
Annals of Otology, Rhinology & Laryngology, 1989Dizziness as defined herein will include an illusion of motion caused by various degrees of ischemia to the vestibular pathway or its interconnecting pathways. “Syndrome,” such as the lateral medullary syndrome, denotes a macroinfarct, while a microinfarct or an area of incomplete infarct (where there may develop an incomplete degeneration of the ...

Transcranial Doppler ultrasonography in patients with Moyamoya disease
Clinical Neurology and Neurosurgery, 1997This study included 17 patients (five men and 12 women) with clinical diagnosis of Moyamoya disease from conventional angiograms. Bilateral basal arteries were measured by the transtemporal approach with a 2 MHz pulsed Doppler instrument (TC-2 64B EME). In 28 out of the 34 basal arteries (82.4%), reliable recordings were obtained.

Comparison of Duplex and Nonduplex Transcranial Doppler Ultrasonography
Ultrasound Quarterly, 2008Transcranial Doppler ultrasonography is essential in the management of children with sickle cell anemia and is a valuable adjunct to the evaluation of a variety of intracranial pathologies in children and adults, including vasoconstriction caused by subarachnoid hemorrhage, demonstration of major intracranial vessel stenoses or occlusion, determination

TRANSCRANIAL DOPPLER ULTRASONOGRAPHY IN THE NEUROCRITICAL CARE UNIT
Critical Care Clinics, 1997TCD ultrasonography is a noninvasive means to study the cerebral vasculature. By varying the depth and angle of insonation of a pulsed sound wave, the direction and velocity profile of the cerebral arteries can be ascertained. This can be used to identify areas of focal stenosis and increased resistance and to estimate the adequacy of cerebral flow ...
