Measurement of Cerebral Blood Flow Volume by Extracranial Sonography

Measurement of cerebral blood flow volume in healthy adults using color duplex sonography.

Assessment of cerebral blood flow by means of blood-flow-volume measurement.

of Blood-Flow-Volume Measurement To the Editor: With great interest we read in Stroke that a working group around Soustiel1 compared cerebral blood flow (CBF) as measured by xenon clearance technique with blood-flow-volume (BFV) measurements from the internal carotid artery (ICA). Soustiel et al found well-correlated data, ie, correlation coefficients 0.75, in a total of 77 measurements. As a c...

Measurement of Cerebral Blood Flow and Cerebral Blood Volume in Humans Using Washout of Hyperoxic Contrast

Introduction Hyperoxic contrast-enhanced MRI, performed by increasing the inspired fraction of oxygen (FiO2>0.21), have been shown in numerous studies to produce positive contrast enhancement in T2-weighted images based on the blood oxygenation-dependent (BOLD) effect [1],[2],[3]. It has been long thought that hyperoxia substantially alters the hemodynamics of the brain, confounding attempts to...

Assessment of Cerebral Blood Flow by Means of Blood-Flow-Volume Measurement in the Internal Carotid Artery

Background and Purpose—We sought to evaluate a new, angle-independent ultrasonic device for assessment of blood flow volume (BFV) in the internal carotid artery (ICA). Methods—Nineteen patients and 4 healthy volunteers were enrolled in a comparative study conducted in the Care Unit of the Division of Neurosurgery at UCLA Medical Center. All patients had been admitted because of severe brain inj...
