This study uses ex vivo DTI to link microstructural features of atherosclerotic plaques with mechanical properties, showing that uniform microstructures are more prone to rupture.

This paper demonstrates that phosphotungstic acid (PTA) binds preferentially to collagen-rich regions in porcine carotid arteries and human atherosclerotic plaques, enabling non-destructive collagen quantification via 3D micro-CT.

This study examines how excluding zero-pressure configuration and residual stress affects material parameter estimation and stress distribution in carotid bifurcation models derived from in-vivo MRI data.

This study uses QSM to show that magnetic susceptibility of carotid arteries is sensitive to microstructural changes, particularly collagen loss, and finds similar susceptibility between human and porcine arteries.

This study investigates how collagen fibre orientation affects the mechanical properties of human carotid plaque caps and their risk of rupture.

This study examines how microstructural changes in arterial tissue affect diffusion tensor imaging metrics, finding that cell content significantly influences anisotropy and tractography.
