The dynamics of the blood oxygenation level‐dependent (BOLD) response are dependent
on changes in cerebral blood flow, cerebral blood volume and the cerebral metabolic rate of …

The blood-oxygen-level-dependent (BOLD) signal measured in the brain with functional
magnetic resonance imaging (fMRI) during an activation experiment often exhibits …

Arterial spin labeling (ASL) is a magnetic resonance imaging (MRI) method that provides a
highly repeatable quantitative measure of cerebral blood flow (CBF). As compared to the …

With the publication in 2015 of the consensus statement by the perfusion study group of the
International Society for Magnetic Resonance in Medicine (ISMRM) and the EU-COST …

Purpose Assessment of brain hemodynamics without exogenous contrast agents is of
increasing importance in clinical applications. This study aims to develop an MR perfusion …

Arterial spin labeling (ASL) is an MRI technique that was first proposed a quarter of a century
ago. It offers the prospect of non-invasive quantitative measurement of cerebral perfusion …

A model of the signal path in arterial spin labeling (ASL)-based functional magnetic
resonance imaging (fMRI) is presented. Three subtraction-based methods for forming a …

ASL MRI is just beginning to be applied more widely to various neurodegenerative
conditions. Initial data suggest that this methodology may provide similar information to FDG …

Background Adult posttraumatic stress disorder (PTSD) has been characterized by altered
fear‐network connectivity. Childhood trauma is a major risk factor for adult PTSD, yet its …

Purpose MRI methods sensitive to functional changes in cerebral blood volume (CBV) may
map neural activity with better spatial specificity than standard functional MRI (fMRI) …
