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...
متن کاملNon-invasive measurement of cerebral blood volume in volunteers.
Invasive techniques are used for conventional measurements of cerebral blood volume and there is a need for methods which are more readily applicable clinically. We studied 13 healthy volunteers using near infrared spectroscopy and transcranial Doppler sonography. Middle cerebral artery flow velocity (vmca) and changes in cerebral oxygenated haemoglobin (HbO2), deoxygenated Hb (Hb), HbO2 - Hb (...
متن کاملMR measurement of regional relative cerebral blood volume in epilepsy.
The purpose of this study was to evaluate the utility of magnetic resonance (MR) relative cerebral blood volume (rCBV) maps for studying regional hemodynamic changes in interictal and ictal epilepsy patients. Ten epilepsy patients were examined on a 1.5 T MR system. Nine patients were investigated interictally and one patient ictally. In the nine interictal patients, the dynamic plane was defin...
متن کاملAssessment 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...
متن کاملOptimizing dynamic T2* MR imaging for measurement of cerebral blood flow using infusions for cerebral blood volume.
We describe an approach to measuring cerebral blood flow (CBF) based on independent measurements of cerebral blood volume (CBV) and mean transit time (MTT) with calculation of CBF by using the central volume theorem: CBF = CBV / MTT. This permits optimization of the individual acquisitions and analyses. In particular, measurement of CBV during contrast infusion, rather than simultaneously with ...
