متن کاملInterrelationships among regional cerebral blood flow, mean transit time, vascular volume and cerebral vascular resistance.
Interrelationships Among Regional Cerebral Blood Flow, Mean Transit Time, Vascular Volume and Cerebral Vascular Resistance • The simultaneous measurement of regional cerebral blood flow (rCBF), mean transit time (MTT), vascular volume (CVV) and cerebral vascular resistance (CVR) was performed in patients with cerebrovascular diseases. The measurement was made by a gamma-ray scintillation camera...
متن کاملQuantification of cerebral blood flow, cerebral blood volume, and blood-brain-barrier leakage with DCE-MRI.
Dynamic susceptibility contrast MRI (DSC-MRI) is the current standard for the measurement of Cerebral Blood Flow (CBF) and Cerebral Blood Volume (CBV), but it is not suitable for the measurement of Extraction Flow (EF) and may not allow for absolute quantification. The objective of this study was to develop and evaluate a methodology to measure CBF, CBV, and EF from T1-weighted dynamic contrast...
متن کاملThe relationship between cerebral blood flow and volume in humans.
The purpose of this study was to establish the relationship between regional CBF and CBV at normal, resting cerebral metabolic rates. Eleven healthy volunteers were investigated with PET during baseline conditions, and during hyper- and hypocapnia. Values for rCBF and rCBV were obtained using 15O-labelled water and carbon monoxide, respectively. The mean value of rCBF using PET was 62 +/- 18 ml...
متن کاملMeasurement 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...
