Transcranial Doppler ultrasound: Valid, invalid, or both? [PDF]

Journal of Applied Physiology, 2014
despite considerable anatomical knowledge acquired by anatomists three centuries ago, little was known about the brain's circulatory control until the latter half of the 19th century, when Angelo Mosso made the first estimations of human cerebral blood flow (CBF) by observing volume changes in ...

Cerebral artery dilatation maintains cerebral oxygenation at extreme altitude and in acute hypoxia : an ultrasound and MRI study [PDF]

, 2011
Transcranial Doppler is a widely used noninvasive technique for assessing cerebral artery blood flow. All previous high altitude studies assessing cerebral blood flow (CBF) in the field that have used Doppler to measure arterial blood velocity have ...

Joint Metabonomic and Instrumental Analysis for the Classification of Migraine Patients with 677-MTHFR Mutations [PDF]

, 2010
Migraine is a neurological disorder that correlates with an increased risk of cerebrovascular lesions. Genetic mutations of the MTHFR gene are correlated to migraine and to the increased risk of artery pathologies.

The effects of chronic trans-resveratrol supplementation on aspects of cognitive function, mood, sleep, health and cerebral blood flow in healthy, young humans [PDF]

, 2015
Single doses of resveratrol have previously been shown to increase cerebral blood flow (CBF) with no clear effect on cognitive function or mood in healthy adults.

Transcranial Doppler ultrasound to assess cerebrovascular reactivity: reliability, reproducibility and effect of posture [PDF]

, 2013
Transcranial Doppler ultrasound (TCD) allows measurement of blood flow velocities in the intracranial vessels, and can be used to assess cerebral vasodilator responses to a hypercapnic stimulus. The reliability of this technique has not been established,

Validation of a basic neurosonology laboratory for detecting cervical carotid artery stenosis

Neurología (English Edition), 2019
Introduction: Most of the cases of ischaemic stroke in our setting are of atherothrombotic origin. Detecting intracranial and cervical carotid artery stenosis in patients with ischaemic stroke is therefore essential.
