Neurovascular coupling reflects the close temporal and regional linkage between neural
activity and cerebral blood flow. Although providing mechanistic insight, our understanding …

Transcranial Doppler (TCD) ultrasound provides rapid, noninvasive, real-time measures of
cerebrovascular function. TCD can be used to measure flow velocity in the basal arteries of …

Transcranial Doppler (TCD) is a noninvasive ultrasound (US) study used to measure
cerebral blood flow velocity (CBF‐V) in the major intracranial arteries. It involves use of low …

Abstract FORTY-FIVE MEASUREMENTS of diameters of 12 human cerebral arteries were
performed during 10 craniotomies under moderate changes in mean blood pressure and …

Cerebral autoregulation is a complex physiological process composed of both fast and slow
components that may respond differently to different rates and patterns of blood pressure …

Indications for the clinical use of transcranial Doppler (TCD) continue to expand while
scanning protocols and quality of reporting vary between institutions. Based on literature …

The combination of measurements of regional cerebral blood flow (rCBF) and blood velocity
in the middle cerebral arteries (MCA) by transcranial doppler sonography was used to …

Transcranial Doppler (TCD) ultrasonography is a noninvasive bedside monitoring technique
that can evaluate cerebral blood flow hemodynamics in the intracranial arterial vasculature …

Although disorders of cerebral autoregulation are commonly seen in neurosurgical disease,
there is currently no test of autoregulation in widespread use that may be performed safely at …

Background and Purpose—Epidemiological data link heavy snoring to an increased risk for
stroke, an association often ascribed to hypertension and/or sleep apnea. The aim of this …
