Effects of non-physiological blood pressure artefacts on measures of cerebral autoregulation [PDF]

open access: yesarXiv, 2016
Cerebral autoregulation refers to regulation mechanisms that aim to maintain cerebral blood flow approximately constant. It is often assessed by autoregulation index (ARI), which uses arterial blood pressure and cerebral blood flow velocity time series to produce a ten-scale index of autoregulation performance (0 denoting the absence of and 9 the ...

Intra-arterial nimodipine for the treatment of vasospasm due to aneurysmal subarachnoid hemorrhage

open access: yesRomanian Neurosurgery, 2016
The cerebral vasospasm is still considered the most devastating complication for the patients with aneurysmal subarachnoid haemorrhage. The aim of this study was to evaluate the efficiency of intra-arterial nimodipine administration in cerebral vasospasm

Simulation-Based Segmentation of Blood Vessels in Cerebral 3D OCTA Images [PDF]

open access: yesarXiv
Segmentation of blood vessels in murine cerebral 3D OCTA images is foundational for in vivo quantitative analysis of the effects of neurovascular disorders, such as stroke or Alzheimer's, on the vascular network. However, to accurately segment blood vessels with state-of-the-art deep learning methods, a vast amount of voxel-level annotations is ...
