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 …

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 …

Purpose To study and reduce the effect of Gibbs ringing artifact on computed diffusion
parameters. Methods We reduce the ringing by extrapolating the k‐space of each diffusion …

In gradient echo (GRE) imaging, three compartment water modeling (myelin water, axonal
water and extracellular water) in white matter has been demonstrated to show different …

Purpose To map the cerebral metabolic rate of oxygen (CMRO2) by estimating the oxygen
extraction fraction (OEF) from gradient echo imaging (GRE) using phase and magnitude of …

Abstract Background and Purpose The objective is to demonstrate feasibility of separating
magnetic sources in quantitative susceptibility map** (QSM) by incorporating magnitude …

To separate the contributions of paramagnetic and diamagnetic sources within a voxel, a
magnetic susceptibility source separation method based solely on gradient-echo data has …

Objective The objective of this study was to evaluate the whole-brain pattern of oxygen
extraction fraction (OEF), cerebral blood flow (CBF), and cerebral metabolic rate of oxygen …

Introduction In patients with multiple sclerosis (MS), conventional magnetic resonance
imaging (MRI) provides only limited insights into the nature of brain damage with modest …

Purpose The development of a reliable clinical technique for quantitative measurements of
the parameters defining the BOLD effect, ie, oxygen extraction fraction (OEF), and …
