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

open access: yesThe Journal of Physiology, EarlyView.
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

Economic Burden of Sickle Cell Disease: A Retrospective Study of Pediatric and Adult Individuals With Medicaid Coverage From 2016 to 2020

open access: yesAmerican Journal of Hematology, Volume 101, Issue 2, Page 269-280, February 2026.
ABSTRACT There is limited information regarding the contemporary real‐world clinical and financial burden of Medicaid enrollees with sickle cell disease (SCD) in the United States. Using the IBM MarketScan Medicaid database (7/2016–12/2020), individuals with ≥ 3 SCD diagnoses were matched 1:1 on age, gender, and race to individuals without SCD ...

Cerebrovascular ultrasonography: Technique and common pitfalls

open access: yesAnnals of Indian Academy of Neurology, 2013
Although the clinical features in some patients with cerebrovascular ischemia may be ill defined, majority of the patients present with focal neurological deficits caused by an arterial occlusion, and the clinical presentations are usually referable to ...

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 ...

Transcranial brain parenchyma sonography in movement disorders

open access: yesChinese Journal of Contemporary Neurology and Neurosurgery, 2012
The diagnosis and discrimination of movement disorders is very difficult in clinical medicine. We usually make a diagnosis according to symptoms and physical examination when the disease develops to a certain stage, but with few objective criteria ...

Transcranial Doppler ultrasound validation of BOLD‐fMRI cerebral blood flow relationship

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 939-950, February 2026.
Abstract Purpose A precise understanding of the interplay between cerebral blood flow (CBF) and blood oxygen level‐dependent (BOLD) fMRI signals is essential for advancing cerebrovascular research. Although calibrated BOLD approaches often rely on arterial spin labelling (ASL) to estimate CBF, alternative validation using transcranial Doppler ...
