An arch worth revisiting: A study on the feline humeral supracondylar foramen and its evolutionary significance

This study investigates the feline humeral supracondylar foramen using micro-CT, concluding it is likely a ligamentous or aponeurotic structure rather than a homologous counterpart to the human supracondyloid foramen.

Microstructural and mechanical insight into atherosclerotic plaques - an ex vivo DTI study to better assess plaque vulnerability

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.

Phosphotungstic acid (PTA) preferentially binds to collagen-rich regions of porcine carotid arteries and human atherosclerotic plaques using 3D micro-computed tomography (CE-μCT)

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.

Inverse Material Parameter Estimation of Patient Specific Finite Element Models at the Carotid Bifurcation: The Impact of Excluding the Zero Pressure Configuration and Residual Stress

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.

Quantitative susceptibility mapping of carotid arterial tissue ex vivo: assessing sensitivity to vessel microstructural composition

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.

An investigation into the critical role of fibre orientation in the ultimate tensile strength and stiffness of human carotid plaque caps

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

Diffusion tensor imaging and arterial tissue: establishing the influence of arterial tissue microstructure on fractional anisotropy, mean diffusivity and tractography

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