Optimizing cerebral perfusion is key to rescuing salvageable ischemic brain tissue. Despite
being an important determinant of cerebral perfusion, there are no effective guidelines for …

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 …

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

Restoring perfusion to ischemic tissue is the primary goal of acute ischemic stroke care, yet
only a small portion of patients receive reperfusion treatment. Since blood pressure (BP) is …

Purpose To evaluate the accuracy of T2‐based whole‐brain oxygen extraction fraction
(OEF) estimation by comparing it with gold standard 15O‐PET measurements. Methods …

Restoring blood flow to brain tissue at risk of infarction is essential for tissue survival and
clinical outcome. We used cerebral blood flow (CBF) quantified with multiple post-labeling …

Background and Objectives Magnetic resonance susceptibility-weighted imaging (SWI) can
identify small brain blood vessels that contain deoxygenated blood due to its induced …

Quantitative BOLD (qBOLD) MRI allows evaluation of oxidative metabolism of the brain
based purely on an endogenous contrast mechanism. The method quantifies deoxygenated …

Introduction Oxygen extraction fraction (OEF) reflects the balance between oxygen delivery
and consumption. We longitudinally measured OEF in older adults to examine the …

Purpose Multi‐echo gradient‐recalled echo acquisitions for QSM enable optimizing the SNR
for several tissue types through multi‐echo (TE) combination or investigating temporal …
