Transcranial Doppler Ultrasonography

Neurosurgery Clinics of North America, 1994
Transcranial Doppler ultrasonography is an extremely useful adjunct in neurosurgical intensive care. Continuous improvements in TCD equipment as well as computer software have improved examination success and also vessel identification. Recent expanding applications of TCD have also allowed the study of disorders of control of the cerebral circulation.

Advances in transcranial doppler ultrasonography

Current Neurology and Neuroscience Reports, 2008
Transcranial Doppler ultrasonography (TCD) is the only noninvasive real-time neuroimaging modality for the evaluation of characteristics of blood flow in basal intracerebral vessels that adds physiologic information to structural imaging. TCD has been rapidly evolving from a simple noninvasive diagnostic tool to an imaging modality with a broad ...

Transcranial doppler ultrasonography

Journal of neurology, neurosurgery, and psychiatry
Abstract Transcranial Doppler ultrasonography (TCD) is a noninvasive, bedside procedure that can detect blood flow in the proximal cerebral intracranial arteries. TCD has multiple applications, including rapid assessment of anterior circulation blood flow in acute, large-vessel occlusion. For patients with subarachnoid hemorrhage, trends

Intraoperative Use of Transcranial Doppler Ultrasonography

Neurosurgery Clinics of North America, 1996
Transcranial Doppler (TCD) ultrasonography is a diagnostic tool that is well established in the fields of neurology and neurosurgery. There are many potential applications of TCD ultrasonographic monitoring in the perioperative care of the patient at risk of cerebral ischemia, the most important of which are detailed in this article.

Transcranial Doppler Ultrasonography: Year 2000 Update

Journal of Neuroimaging, 2000
In this update, the main clinical applications of transcranial Doppler ultrasonography are reassessed. A specific format for technology assessment, personal experience, and an extensive review of the literature form the basis of the evaluation. The document is approved by the American Society of Neuroimaging and the Neurosonology Research Group of the ...

Transcranial Doppler ultrasonography in intensive care

European Journal of Anaesthesiology, 2008
Transcranial Doppler is an innovative, flexible, accessible tool for the bedside monitoring of static and dynamic cerebral flow and treatment response. Introduced by Rune Aaslid in 1982, it has become indispensable in clinical practice. The main obstacle to ultrasound penetration of the skull is bone. Low frequencies, 1-2 MHz, reduce the attenuation of

Transcranial colour Doppler ultrasonography

Rivista di Neuroradiologia, 2001
Transcranial 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.

Transcranial Doppler Ultrasonography

2019
Abstract Transcranial Doppler (TCD) ultrasonography is a diagnostic technology for ascertaining numerous physiologic and pathologic phenomena by monitoring the direction and velocity of blood flow in intracranial vasculature. It is a noninvasive, point-of-care diagnostic tool that provides continuous and reproducible bedside data without

Principles of Transcranial Doppler Ultrasonography

2020
Transcranial 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.
