In MRI, the main magnetic field polarizes the electron cloud of a molecule, generating a
chemical shift for observer protons within the molecule and a magnetic susceptibility …

Cerebrovascular reactivity (CVR) is an indicator of cerebrovascular reserve and provides
important information about vascular health in a range of brain conditions and diseases …

Functional magnetic resonance imaging (fMRI) has been used to infer age-differences in
neural activity from the hemodynamic response function (HRF) that characterizes the blood …

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 …

Functional magnetic resonance imaging (fMRI) using the blood oxygenation level-
dependent (BOLD) contrast indirectly probes neuronal activity changes via evoked cerebral …

Over the last decade, the brain's default‐mode network (DMN) and its function has attracted
a lot of attention in the field of neuroscience. However, the exact underlying mechanisms of …

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

Over the last two decades, numerous human MRI studies of neuroplasticity have shown
compelling evidence for extensive and rapid experience-induced brain plasticity in vivo. To …

The BOLD contrast mechanism has a complex relationship with functional brain activity,
oxygen metabolism, and neurovascular factors. Accurate interpretation of the BOLD signal …

We aimed to validate oxygen extraction fraction (OEF) estimations by quantitative
susceptibility mapping plus quantitative blood oxygen-level dependence (QSM+ qBOLD, or …
