Magnetic resonance elastography (MRE) is an MRI technique for imaging the mechanical properties of brain in vivo, and has shown differences in properties between neuroanatomical regions and sensitivity to aging, neurological disorders, and ...
An inverse modelling study on the local volume changes during early morphoelastic growth of the fetal human brain [0.03%]
胎儿人大脑形态弹性生长早期阶段局部体积变化的逆向建模研究

We take a data-driven approach to deducing the local volume changes accompanying early development of the fetal human brain. Our approach uses fetal brain atlas MRI data for the geometric changes in representative cases. Using a nonlinear c...
In vivo estimates of axonal stretch and 3D brain deformation during mild head impact [0.03%]

The rapid deformation of brain tissue in response to head impact can lead to traumatic brain injury. In vivo measurements of brain deformation during non-injurious head impacts are necessary to understand the underlying mechanisms of trauma...
