Fig 4. Effect of ventricular enlargement on brain tissue deformation and stiffness in adult hydrocephalic rats.
Relationships between the ventricle system cross-sectional area and (a) the cranial cross-sectional area, (b) cortical gray matter thickness, (c) caudate-putamen cross-sectional area, and shear modulus (G*) of the (d) cortical gray matter and (e) caudate-putamen in adult hydrocephalic rats. Relationships were evaluated using generalized estimating equations accounting for the repeated measures. For relationships that were significant, the parameter B represents the increase in that parameter per mm2 of ventricle system area.
