Background Predicting progression to aortic valve replacement (AVR) in moderate aortic stenosis (AS) is challenging. This ...

In a recent study published in Scientific Reports, researchers combined four-dimensional (4D) flow magnetic resonance imaging (MRI) with three-dimensional printing to map blood flow in a pulsating ...

This study aimed to determine if stress cardiac MRI testing (a heart scan that measures blood flow with magnetic resonance imaging) could help improve diagnosis and treatment for people with suspected ...

OAK BROOK, Ill. - Healthy men and women have different blood flow characteristics in their hearts, according to a new study published in the journal Radiology: Cardiothoracic Imaging. Researchers said ...

A research paper by scientists from Beihang University proposed a machine learning (ML)-driven cerebral blood flow (CBF) prediction model, featuring multimodal imaging data integration and an ...

For almost three decades, functional magnetic resonance imaging (fMRI) has been one of the main tools in brain research. Yet a new study published in Nature Neuroscience fundamentally challenges the ...

Jan. 22 (UPI) --Overall brain activity declines during light stages of sleep, even as communication between different brain regions becomes "much more dynamic," according to the researchers behind a ...

A new study fundamentally challenges how fMRI data are interpreted, finding no valid coupling between oxygen content measured ...
