Head position and cerebral blood flow velocity in acute ischemic stroke: a systematic review and meta-analysis.
(Karger, 2014)
BACKGROUND:
Patients with acute ischemic stroke (AIS) have impaired vasomotor reactivity, especially in the affected cerebral hemisphere, such that they may depend directly on systemic blood pressure to maintain perfusion ...

Relationship of antral follicular blood flow velocity to superovulatory responses in ewes
(Elsevier B.V., 2017-07-01)
The aim of this study was to examine the association between antral follicular blood flow velocity and the response of ewes to hormonal ovarian superstimulation. Ten Santa Ines ewes were subjected to a short- (7 days; Group ...
Estimation and significance testing of cross-correlation between cerebral blood flow velocity and background electro-encephalograph activity in signals with missing samples
(Medical and Biological Engineering and Computing, 2001-02-23)
Cross-correlation between cerebral blood flow (CBF) and background EEG activity can indicate the integrity of CBF control under changing metabolic demand. The difficulty of obtaining long, continuous recordings of good ...
Flat-head positioning increases cerebral blood flow in anterior circulation acute ischemic stroke. A cluster randomized phase IIb trial.
(Sage Publications, 2017-09-11)
Background Whether lying-flat improves blood flow in patients with acute ischemic stroke is unknown. Our aim was to investigate if lying-flat "changes" cerebral blood flow velocities assessed by transcranial Doppler in ...

Automatic correction of background phase offset in 4D-flow of great vessels and of the heart in MRI using a third-order surface model
(Springer, 2019-12)
Objective: To evaluate an automatic correction method for velocity offset errors in cardiac 4D-flow acquisitions. Materials and methods: Velocity offset correction was done in a plane-by-plane scheme and compared to a ...
