To simulate blood flow inside brain aneurysms, researchers from Japan have developed a computational method that combines 4D ...

A fourth order linear finite impulse response (FIR) model of cerebral blood flow velocity (CBFV) as a function of mean arterial blood pressure (MABP) was investigated. The Kalman filter estimation was ...

Researchers at Leipzig University's Carl Ludwig Institute have discovered that in the cerebral cortex, synaptic signal ...

Brain swelling, or cerebral edema, is a medical emergency. Learn about the evidence-based treatments doctors use to reduce ...

In future, MR cerebral perfusion measurements on brain tissue level using arterial spin labeling MRI may be possible; however, this sequence takes a longer amount of time and may decrease the ...

Conclusions CPR with FVO significantly increased mean arterial pressure, cardiac perfusion, and cerebral perfusion over CPR alone. These findings suggest FVO may represent a novel adjunctive strategy ...

Volume expansion improves blood pressure and cerebral perfusion pressure. Improved perfusion yields better oxygenation to areas of the brain that are at risk for secondary damage (Doyle et al ...

Introduction Impaired cerebral autoregulation is associated with postoperative ischaemic brain injury and often occurs in patients with carotid artery stenosis. Adequate cerebral perfusion should ...

Objective Blood pressure (BP) lowering may increase stroke risk in patients with symptomatic major cerebral artery disease and impaired perfusion. To investigate the relationships among BP, impaired ...

Simply stated, increases in pressure produce depolarization of vascular muscle, likely via activation of transient receptor potential channels, resulting in increases in intracellular calcium and ...
