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

open access: yesMagnetic Resonance in Medicine, EarlyView.
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 Doppler ultrasound validation of BOLD‐fMRI cerebral blood flow relationship

open access: yesMagnetic Resonance in Medicine, EarlyView.
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 ...

Acute hemichorea‐hemiballism as the initial sign of cortical cerebral infarction: A case report

open access: yesNeuroprotection, EarlyView.
Abstract Hemichorea‐hemiballism is classically associated with the contralateral basal ganglia, particularly involving the putamen and subthalamic nucleus, whereas cortical involvement remains a rare etiology. In this case, we present a patient with acute hemichorea‐hemiballism secondary to multiple cortical infarcts demonstrated by neuroimaging.
