Optimization of pseudo‐continuous arterial spin labeling for brain perfusion imaging in the intraoperative setting

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 1123-1134, February 2026.
Abstract Purpose Pseudo‐continuous arterial spin labeling (PCASL) efficiency during intraoperative MRI is degraded due to large field inhomogeneities observed in some patients and lower arterial blood velocities induced by anesthesia. The purpose of this work was to maximize labeling efficiency during intraoperative MRI by optimizing PCASL parameters ...

A systematic review of brain health in adults with chronic pain

open access: yesAnaesthesia, Volume 81, Issue 2, Page 248-262, February 2026.
Summary Introduction Recent research has linked chronic pain with an increased risk of clinical dementia diagnosis. Yet structural and functional brain changes associated with chronic pain and their potential role in accelerating brain ageing have not been characterised comprehensively.

Quantification of the cerebral pressure–flow relationship directional sensitivity: Reliability of shorter repeated squat–stand durations

open access: yesExperimental Physiology, Volume 111, Issue 2, Page 357-374, 1 February 2026.
Abstract The magnitude of changes in middle cerebral artery mean blood velocity (MCAv) is attenuated when mean arterial pressure (MAP) increases compared with when MAP decreases. This directional sensitivity has been characterized using a time‐corrected ratio calculated on MCAv and MAP changes induced by repeated squat–stands (RSS) at 0.05 and 0.10 Hz ...

Hemodynamic predictors of early neurological deterioration and clinical outcome after endovascular treatment in large artery occlusion

open access: yesHeliyon
Objective: Half of the patients with acute large artery occlusion (LAO) have poor outcomes after endovascular treatment (EVT). Early complications such as cerebral edema and symptomatic intracranial hemorrhage (sICH) can lead to early neurological ...

Sex differences in cerebral pulsatility and damping: A 4D flow MRI study

open access: yesExperimental Physiology, Volume 111, Issue 2, Page 568-579, 1 February 2026.
Abstract Cerebral pulsatility is a potential marker of cerebrovascular health, yet little is understood about sex differences in cerebral pulsatility with age, especially within different cerebral arteries. Additionally, cerebral damping can blunt cerebral pulsatility and might decline with age.

A comparative analysis of transcranial Doppler parameters acquired during carotid stenting and semi-eversion carotid endarterectomy

open access: yesJornal Vascular Brasileiro
Background Carotid endarterectomy (CEA) and carotid artery stenting (CAS) have both been proposed for treatment of critical atherosclerotic stenosis located at the carotid bifurcation. Monitoring of hyperintense microembolic signals (MES) by transcranial

Effect of moderate altitude and nocturnal oxygen therapy on cerebrovascular function in patients with COPD: A randomized, crossover trial at 2048 m

open access: yesExperimental Physiology, Volume 111, Issue 2, Page 527-538, 1 February 2026.
Abstract We investigated whether nocturnal oxygen therapy improves next‐day cerebrovascular function in lowlanders with chronic obstructive pulmonary disease (COPD) staying at moderate altitude. This randomized, placebo‐controlled single‐blind crossover trial was performed in moderate‐to‐severe COPD patients [forced expiratory volume in 1 s (FEV1 ...

Longitudinal sex differences in cerebrovascular ageing in older adults: results from the brain in motion study

open access: yesThe Journal of Physiology, Volume 604, Issue 3, Page 1088-1112, 1 February 2026.
Abstract figure legend Longitudinal assessment of sex differences in cerebrovascular ageing over a ∼6 year period: the Brain in Motion study. Cerebrovascular function was assessed at baseline (T1) and at a follow‐up (T2) ∼6 years later, at rest, during euoxic hypercapnia and while engaging in submaximal exercise. Over the follow‐up period females had a

Advances in the study methods of cerebral venous sinus hemodynamics

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery
Cerebral venous system diseases can lead to idiopathic intracranial hypertension (IIH), cerebral venous thrombosis (CVT) and pulsatile tinnitus (PT), and accurate evaluation of cerebral venous sinus hemodynamics is very important for the diagnosis and ...
