Prominent cerebral veins on susceptibility‐weighted angiography in acute meningoencephalitis [PDF]

open access: yesBrain and Behavior, 2023
Background and purpose We have commonly observed prominent cerebral veins on susceptibility‐weighted angiography (SWAN) in acute meningoencephalitis. This study aimed to investigate the clinical significance of these findings.

Arterial-optimized 4D-flow MRI for quantifying flow and pulsatility in venous sinuses and large cerebral veins [PDF]

open access: yesScientific Reports
A single, arterial-optimized 4D-flow MRI acquisition may enable fast assessment of both cerebral arterial and venous flow. However, arteries and veins require different velocity encoding (VENC) settings for optimal velocity-to-noise ratio (VNR ...

Cortical depth dependent functional responses in humans at 7T: improved specificity with 3D GRASE [PDF]

open access: yes, 2013
Ultra high fields (7T and above) allow functional imaging with high contrast-to-noise ratios and improved spatial resolution. This, along with improved hardware and imaging techniques, allow investigating columnar and laminar functional responses.

Usefulness of the Multimodal Fusion Image for Visualization of Deep Sylvian Veins

open access: yesNeurologia Medico-Chirurgica, 2022
The preoperative assessment of cerebral veins is important to avoid unexpected cerebral venous infarction in the neurosurgical setting. However, information is particularly limited regarding deep Sylvian veins, which occasionally disturb surgical ...

Separation of cortical arteries and veins in optical neurovascular imaging [PDF]

open access: yesJournal of Innovative Optical Health Sciences, 2014
Separation of arteries and veins in the cerebral cortex is of significant importance in the studies of cortical hemodynamics, such as the changes of cerebral blood flow, perfusion or oxygen concentration in arteries and veins under different pathological
