Inter-vendor reproducibility of pseudo-continuous arterial spin labeling at 3 Tesla. [PDF]

open access: yesPLoS ONE, 2014
PURPOSE:Prior to the implementation of arterial spin labeling (ASL) in clinical multi-center studies, it is important to establish its status quo inter-vendor reproducibility.

Opioid suppression of conditioned anticipatory brain responses to breathlessness [PDF]

open access: yes, 2017
© 2017 The Authors Opioid painkillers are a promising treatment for chronic breathlessness, but are associated with potentially fatal side effects. In the treatment of breathlessness, their mechanisms of action are unclear.

Non-contrast renal magnetic resonance imaging to assess perfusion and corticomedullary differentiation in health and chronic kidney disease [PDF]

open access: yes, 2016
AIMS Arterial spin labelling (ASL) MRI measures perfusion without administration of contrast agent. While ASL has been validated in animals and healthy volunteers (HVs), application to chronic kidney disease (CKD) has been limited. We investigated the

Investigation of the neurovascular coupling in positive and negative BOLD responses in human brain at 7T [PDF]

open access: yes, 2014
Decreases in stimulus-dependent blood oxygenation level dependent (BOLD) signal and their underlying neurovascular origins have recently gained considerable interest.

Cerebral vasoreactivity in response to a headof-bed position change is altered in patients with moderate and severe obstructive sleep apnea [PDF]

open access: yes, 2018
Obstructive sleep apnea (OSA) can impair cerebral vasoreactivity and is associated with an increased risk of cerebrovascular disease. Unfortunately, an easy-to-use, non-invasive, portable monitor of cerebral vasoreactivity does not exist. Therefore, we

Current and Future Applications of Arterial Spin Labeling MRI in Cerebral Arteriovenous Malformations

open access: yesBiomedicines
Arterial spin labeling (ASL) has emerged as a promising noninvasive tool for the evaluation of both pediatric and adult arteriovenous malformations (AVMs). This paper reviews the advantages and challenges associated with the use of ASL in AVM assessment.

Arterial Spin Labeling MRI in Carotid Stenosis: Arterial Transit Artifacts May Predict Symptoms.

open access: yesRadiology, 2020
BackgroundStenosis of the internal carotid artery has a higher risk for stroke. Many investigations have focused on structure and plaque composition as signs of plaque vulnerability, but few studies have analyzed hemodynamic changes in the brain as a ...

Selective Arterial Spin Labeling

open access: yesTopics in Magnetic Resonance Imagin, 2016
Knowledge of the distribution of blood flowing from the heart to the brain-feeding arteries is important for the understanding and diagnosis of cerebrovascular diseases. Due to anatomical variations and anomalies within the cerebrovasculature, together with changes caused by various cerebrovascular diseases, there is high variability in the ...

Arterial Spin Labeling: Experiência Inicial, Indicações Clínicas e Dificuldades

open access: yesActa Médica Portuguesa, 2012
O arterial spin labeling (ASL) é uma técnica de perfusão por ressonância magnética (RM) que usa os protões das moléculas de água do sangue arterial como marcador endógeno.
