Researchers at the University of East Anglia have developed cutting-edge imaging technology to help doctors better diagnose and monitor patients with heart failure. The state-of-the-art technology ...

Researchers from Science Tokyo develop a new computational method that combines 4D MRI, CFD, and DA for faster and realistic blood flow analysis in brain aneurysms. To simulate blood flow inside brain ...

Four-dimensional flow cardiovascular MRI (4D flow CMR) can more accurately estimate peak aortic valve velocities (V Peak) than traditional transthoracic echocardiography (TTE) in patients with aortic ...

Researchers have developed cutting-edge technology to diagnose patients with heart failure in record time. The state-of-the-art technology uses magnetic resonance imaging (MRI) to create detailed 4D ...

Advanced imaging, like 4D-flow CMR, aids in understanding PA remodeling in different PH subtypes, offering non-invasive differentiation. PAH patients exhibit distinct PA flow characteristics, ...
