Parkinson's disease (PD) is characterized by a progressive loss of dopaminergic neurons.
Exercise has been reported to slow the clinical progression of PD. We evaluated the …

Putative MRI markers of iron in deep gray matter have demonstrated age related changes
during discrete periods of healthy childhood or adulthood, but few studies have included …

Object This study evaluates inter-site and intra-site reproducibility at ten different 7 T sites for
quantitative brain imaging. Material and Methods Two subjects–termed the “traveling heads” …

Prediction of disease progression is challenging in multiple sclerosis as the sequence of
lesion development and retention of inflammation within a subset of chronic lesions is …

Introduction We present the reliability of ultra-high field T 2* MRI at 7T, as part of the UK7T
Network's “Travelling Heads” study. T 2*-weighted MRI images can be processed to produce …

ABSTRACT BACKGROUND AND PURPOSE Ultrahigh‐field 7T promises more than
doubling the signal‐to‐noise ratio (SNR) of 3T for magnetic resonance imaging (MRI) …

MRI-based oxygen extraction fraction imaging has a great potential benefit in the selection
of clinical strategies for ischemic stroke patients. This study aimed to evaluate the …

Background In people with multiple sclerosis (pwMS), lesions with a hyperintense rim (rim+)
on Quantitative Susceptibility Map** (QSM) have been shown to have greater myelin …

Quantitative susceptibility map** (QSM) is an MRI-based, computational method for
anatomically localizing and measuring concentrations of specific biomarkers in tissue such …

Abstract Background and Purpose We investigated the effects of aging, white matter
hyperintensities (WMH), and cognitive impairment on brain iron levels and cerebral oxygen …
