Regional Stiffness and Hardening Indices: New Indicators Derived from Multidimensional Dynamic CTA for Aneurysm Risk Assessment. [PDF]
Adv Sci (Weinh)Two new indicators are derived from nonlinear stress–strain behavior obtained through in vivo biomechanical analysis of patient‐specific multidimensional dynamic computed tomography angiography. The regional stiffness index indicates the average stiffness while the hardening index reflects the pace of strain hardening.
