The human brain constitutes 2% of the body's total mass but uses 20% of the oxygen. The
rate of the brain's oxygen utilization can be derived from a knowledge of cerebral blood flow …

The quantitative evaluation of brain hemodynamics and metabolism, particularly the
relationship between brain function and oxygen utilization, is important for the …

Purpose To demonstrate acquisition and processing methods for quantitative oxygenation
venograms that map in vivo oxygen saturation (SvO2) along cerebral venous vasculature …

Purpose To quantitatively map cerebral metabolic rate of oxygen () and oxygen extraction
fraction () in human brains using quantitative susceptibility map** (QSM) and arterial spin …

The brain depends almost entirely on oxidative metabolism to meet its significant energy
requirements. As such, the cerebral metabolic rate of oxygen (CMRO2) represents a key …

Purpose Our objective was to demonstrate the feasibility of using hyperventilation as an
efficient vasoconstrictive challenge and prior knowledge as denoising constraints for …

The magnetism of hemoglobin–being paramagnetic in its deoxy and diamagnetic in its oxy
state–offers unique opportunities to probe oxygen metabolism in blood and tissues. The …

We present a technique for quantifying global cerebral metabolic rate of oxygen
consumption (CMRO2) in absolute physiologic units at 3-second temporal resolution and …

Purpose The objective of this study was to demonstrate the feasibility of a cerebral metabolic
rate of oxygen (CMRO2) map** method based on its minimum local variance (MLV) …

Background The function of the peripheral microvascular may be interrogated by measuring
perfusion, tissue oxygen concentration, or venous oxygen saturation (SvO 2) recovery …
