Ultrasound (US) is acoustic energy that interacts with human tissues, thus, producing
bioeffects that may be hazardous, especially in sensitive organs (ie, brain, eye, heart, lung …

Restoring perfusion to ischemic tissue is the primary goal of acute ischemic stroke care, yet
only a small portion of patients receive reperfusion treatment. Since blood pressure (BP) is …

Transcranial Doppler (TCD) is a rapid and non-invasive diagnostic technique that can
provide real-time measurements of the relative changes in cerebral blood velocity (CBV) …

Unhealthy vascular aging promotes atherogenesis, which may lead to significant internal
carotid artery stenosis (CAS) in 5 to 7.5% of older adults. The pathogenic factors that …

Assessment of distal cerebral perfusion after ischaemic stroke is currently only possible
through expensive and time-consuming imaging procedures which require the injection of a …

We investigated the effects of atherosclerosis in the carotid region on cerebral
haemodynamics. A total of 15 stenosis cases following NASCET criteria were modelled …

Traditional diagnosis of patent foramen ovale (PFO) in the heart has involved the use of
transcranial Doppler (TCD). However, TCD is essentially a blind test that cannot directly …

Progression of carotid stenosis (CS) significantly reduces blood flow in the affected arteries
and alters both proximal and distal hemodynamics. While conventional studies consider …

Ischemic stroke can arise from the sudden occlusion of a brain-feeding artery by a clot
(embolic), or local thrombosis. Hemodynamic stroke occurs when blood flow does not …

Objective. This study explored the clinical application value of image denoising algorithm
combined with Doppler ultrasound imaging in evaluation of aspirin combined with low …
