Collateral circulation is a potent predictor of revascularization and clinical outcomes after acute ischemic stroke, and various features of collateral flow may be seen with a variety of neuroimaging ...

In patients undergoing endovascular therapy for acute ischemic stroke, the presence of collateral blood flow increases the likelihood of reperfusion and good functional outcome, according to a ...

In patients with good collateral pial circulation in the brain, clinicians may be able to further extend the time window for endovascular treatment in stroke patients beyond that of subjects with poor ...

A Doppler ultrasound is a test that uses high-frequency sound waves to measure the amount of blood flow through your arteries and veins, usually those that supply blood to your arms and legs. Vascular ...

Continuous monitoring The conformal ultrasound patch enables volumetric mapping of the major arteries in the brain and recording of blood flow spectra. The patch consists of an array of piezoelectric ...

Engineers have developed a wearable ultrasound patch that can offer continuous, non-invasive monitoring of blood flow in the brain. The soft and stretchy patch can be comfortably worn on the temple to ...
