Focused ultrasound with microbubbles is a noninvasive procedure that transiently opens the blood-brain barrier (BBB) using low-intensity sound waves. The openings reseal within 24 hours. Using MRI to ...

Growing evidence indicates that the brain’s microvascular system plays a key role in neurological diseases and aging. This is especially true for capillaries, the smallest blood vessels, that interact ...

3D coronary mapping Left: 3D microbubble density map visualizes the entire coronary microcirculation network of an isolated pig heart. Right: 3D flow map showing arterial (red) and venous (blue) flow.

In China, the healthcare burden of cardiovascular diseases (CVDs) will continue to rise due to the pressure of the aging population, which has posed higher demands for CVDs prevention and treatment.

Expanding the approval to pediatric patients is expected to improve the diagnostic accuracy of echocardiograms. The Food and Drug Administration (FDA) has approved Optison ™ (perflutren protein-type A ...

The study of the human phenome is essential for understanding the complexities of wellness and disease and their transitions, with molecular imaging being a vital tool in this exploration. Molecular ...

Right-to-left shunt, mainly due to patent foramen ovale (PFO), is likely responsible for ≈5% of all ischemic strokes and 10% of those occurring in young and middle-aged adults. Randomized clinical ...

Abstract: In an increasing number of applications of focused ultrasound (FUS) therapy, such as opening of the blood-brain barrier or collapsing microbubbles in a tumor, elevation of tissue temperature ...

The tumor microenvironment (TME) has a crucial role in tumor development, metastasis, and recurrence. The chaotic and complex physical structure of the TME not only limits drug delivery but also ...

St. Paul-based medtech startup Agitated Solutions (ASI) has been given the green light to begin selling its post-stroke diagnostic device in Canada. Earlier this month, the company announced that it ...

Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

Abstract: Contrast enhanced ultrasound is a radiation-free imaging modality which uses encapsulated gas microbubbles for improved visualization of the vascular bed deep within the tissue. It has ...
