Researchers at Rice University and Oak Ridge National Laboratory have unveiled a physics-based model of magnetic resonance relaxation that bridges molecular-scale dynamics with macroscopic magnetic ...

Compared to other imaging modalities like X-rays or CT scans, MRI scans provide high-quality soft tissue contrast. Unfortunately, MRI is highly sensitive to motion, with even the smallest of movements ...

Aviv Mezer and colleagues at the Hebrew University of Jerusalem have developed a mathematical model that compares the water content of the brain with measures of physical properties obtained from MRI ...
