Noncontrast MRI Assessment of Oxygen Metabolism in Human Calf Muscles Using VSASL and ANN‐Based GESSE [PDF]

NMR Biomed
Workflow (Steps 1–4): Both MBF and MOEF maps were registered to a T2‐weighted fat‐suppressed structural image using rigid or affine transformations in 3D Slicer. The gastrocnemius, soleus, and tibialis anterior muscles were segmented in 3D volumes, and the resulting segmentations were used as masks to propagate to all parameter maps to extract regional

Disentangling the effect of brain insulin resistance on brain health (BIR‐BrainHealth): Rationale and study protocol

Diabetic Medicine, EarlyView.
Abstract Aims Insulin signalling in the brain is crucial for systemic metabolic regulation and cognitive function. In some individuals, these effects are reduced, a phenomenon referred to as brain insulin resistance (BIR). This condition may contribute to the elevated risk of cognitive decline and dementia in diabetes, yet its prevalence, mechanisms ...

Uncovering the impact of the cardiovascular system on cerebrovascular health using MRI

Experimental Physiology, EarlyView.
Abstract Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration ...

Lower cerebral blood flow but not cerebrovascular response in elastin haploinsufficient mice

Experimental Physiology, EarlyView.
Abstract Elastin insufficiency is associated with structural differences in the large elastic arteries and cerebral artery dysfunction. However, previous studies have not assessed potential sex differences in cerebrovascular function. We measured cerebral blood flow (CBF) using arterial spin labeling MRI at rest and in response to hypercapnia challenge

Cerebrovascular regulation during heat stress

Experimental Physiology, EarlyView.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

Additional Role of 3D ASL Perfusion in Skull Base Lesions

Indian Journal of Radiology and Imaging
Background Arterial spin labeling (ASL) perfusion imaging is widely used since its main advantage is that no intravenous contrast is needed.

Magnetic resonance imaging of cerebral blood flow in animal stroke models

Brain Circulation, 2016
Perfusion could provide useful information on the metabolic status and functional status of tissues and organs. This review summarizes the most commonly used perfusion measurement methods: Dynamic susceptibility contrast (DSC) and arterial spin labeling (

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

Experimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...
