Transcranial Doppler Ultrasound
2017The purpose of perioperative and critical care transcranial Doppler (TCD) ultrasonographic monitoring is to assess cerebral perfusion change. This is accomplished through noninvasive continuous measurement of blood flow-velocity within the largest intracranial blood vessels.

Transcranial ultrasound in the diagnosis of Parkinson's disease
Nature Clinical Practice Neurology, 2008This Practice Point commentary discusses a prospective study by Gaenslen et al. regarding the diagnostic value of transcranial ultrasound in patients with early features of parkinsonism. Reference diagnoses were obtained on the basis of repeated clinical examination over the course of 1 year and by the performance of functional imaging in uncertain ...

MR-Guided Transcranial Focused Ultrasound
2016Previous chapters introduced the ability of using focused ultrasound to ablate tissues. It has led to various clinical applications in the treatment of uterine fibroid, prostate or liver cancers. Nevertheless, treating the brain non-invasively with focused ultrasound has been considered beyond reach for almost a century: The skull bone protects the ...

Transcranial ultrasound hemorrhage detector
The Journal of the Acoustical Society of America, 2014The present state-of-the-art technology in clinical neurosonography requires an acoustic window to achieve a sufficient signal-to-noise ratio (SNR) for detection of intracranial hemorrhage (ICrH). Conventional clinical practices use ultrasound in the range of 2–10 MHz to image and diagnose patients, a frequency range that is too high to produce high ...

[Transcranial Doppler ultrasound].
Canadian Association of Radiologists journal = Journal l'Association canadienne des radiologistes, 1992Over the last decade, transcranial Doppler examination of the cerebral vessels has been made possible by the development of a high-intensity, low-frequency (2 MHz) pulse probe. The middle, the anterior and the posterior cerebral arteries, the cavernous portion of the carotid artery and the basilar artery can thus be easily studied transtemporally or ...

Transcranial focused ultrasound in the human brain
NeuronMany patients suffering with neurological and psychiatric disorders remain disabled despite modern medical and surgical approaches. Novel, safe, minimally invasive, and widely deployable therapies are urgently needed. Recent advances in focused ultrasound technology are opening a number of new therapeutic frontiers.

Transcranial and Cervical Ultrasound in Stroke
2017Abstract Transcranial Doppler (TCD) and cervical duplex ultrasound (CDU) offer insights into acute stroke mechanisms and provide real-time information for clinical decision making in acute stroke patients, selection for, and monitoring effects of therapeutic interventions. Both tests can be repeatedly performed at bedside.

Transcranial Ultrasound in the Neurocritical Care Unit
Neuroimaging Clinics of North AmericaUltrasound evaluation of the brain is performed through acoustic windows. Transcranial Doppler has long been used to monitor patients with subarachnoid hemorrhage for cerebral vasospasm. Transcranial color-coded sonography permits parenchymal B-mode imaging and duplex evaluation.
