DOI: 10.1002/jmri.28315
Abstract: A typical stroke MRI protocol includes perfusion‐weighted imaging (PWI) and MR angiography (MRA), requiring a second dose of contrast agent. A deep learning method to acquire both PWI and MRA with single dose can resolve… read more here.

DOI: 10.3389/fneur.2022.1051397
Abstract: Stroke is a major cause of death or disability. As imaging-based patient stratification improves acute stroke therapy, dynamic susceptibility contrast magnetic resonance imaging (DSC-MRI) is of major interest in image brain perfusion. However, expert-level perfusion… read more here.
