Magnetic resonance imaging determination of tissue sodium across the CKD spectrum – associations and implications for health Open
Background and Hypothesis Increased tissue sodium (Na+) concentration is associated with adverse clinical outcomes in people with chronic kidney disease (CKD) including hypertension, inflammation and increased cardiovascular disease (CVD).…

Oxygen extraction fraction changes in ischemic tissue from 24–72 hours to 12 months after successful reperfusion Open
Oxygen Extraction Fraction (OEF) is a critical measure of a tissue’s metabolic state post-ischemic stroke. This study investigated OEF changes in stroke-affected tissue compared to healthy tissue, post-reperfusion. OEF maps generated from …

3T sodium-MRI as predictor of neurocognition in nondemented older adults: a cross sectional study Open
Dementia is a burgeoning global problem. Novel magnetic resonance imaging (MRI) metrics beyond volumetry may bring new insight and aid clinical trial evaluation of interventions early in the Alzheimer’s disease course to complement existin…

Baseline White Matter Is Associated With Physical Fitness Change in Preclinical Alzheimer’s Disease Open
White matter (WM) microstructure is a sensitive marker to distinguish individuals at risk of Alzheimer's disease. The association of objective physical fitness (PF) measures and WM microstructure has not been explored and mixed results rep…

Clinical Integration of Automated Processing for Brain Quantitative Susceptibility Mapping: Multi‐Site Reproducibility and Single‐Site Robustness Open
BACKGROUND AND PURPOSE Quantitative susceptibility mapping (QSM) of the brain has become highly reproducible and has applications in an expanding array of diseases. To translate QSM from bench to bedside, it is important to automate its re…

Association between structural changes in brain with muscle function in sarcopenic older women: the women's healthy ageing project (WHAP). Open
OBJECTIVES: The involvement of changes in brain structure in the pathophysiology of muscle loss (sarcopenia) with aging remains unclear. In this study, we investigated the associations between brain structure and muscle strength in a group…

Sleep Duration and Subsequent Cortical Thinning in Cognitively Normal Older Adults Open
Among cognitively normal older adults, sleep durations of < 7 h and > 7 h may increase the rate of subsequent frontotemporal gray matter atrophy. Additional studies, including those that use objective sleep measures and investigate mechani…

Bootstrapping white matter segmentation, Eve++ Open
Multi-atlas labeling has come in wide spread use for whole brain labeling on magnetic resonance imaging. Recent challenges have shown that leading techniques are near (or at) human expert reproducibility for cortical gray matter labels. Ho…
