Effect of interstitial fluid pressure on shear wave elastography : an experimental and computational study Ghent University
Objective. An elevated Interstitial Fluid Pressure (IFP) can lead to strain-induced stiffening of poroelastic biological tissues. As Shear Wave Elastography (SWE) measures functional tissue stiffness based on the propagation speed of acoustically induced shear waves, the Shear Wave Velocity (SWV) can be used as an indirect measurement of the IFP. The underlying biomechanical principle for this stiffening behavior with pressurization is however ...
Uncertainty quantification of the wall thickness and stiffness in an idealized dissected aorta Ghent University KU Leuven
Personalized treatment informed by computational models has the potential to markedly improve the outcome for patients with a type B aortic dissection. However, existing computational models of dissected walls significantly simplify the characteristic false lumen, tears and/or material behavior. Moreover, the patient-specific wall thickness and stiffness cannot be accurately captured non-invasively in clinical practice, which inevitably leads to ...

Transmural wave speed gradient may distinguish intrinsic myocardial stiffening from preload-induced changes in operational stiffness in shear wave elastography Ghent University KU Leuven
Background: Shear wave elastography (SWE) is a promising technique to non-invasively assess myocardial stiffness based on the propagation speed of mechanical waves. However, a high wave propagation speed can either be attributed to an elevated intrinsic myocardial stiffness or to a preload-induced increase in operational stiffness. Objective: Our objective was to find a way to discriminate intrinsic myocardial stiffening from stiffening caused ...
The impact of geometry, intramural friction, and pressure on the antegrade longitudinal motion of the arterial wall : a phantom and finite element study Ghent University
Longitudinal motion of the carotid arterial wall, as measured with ultrasound, has shown promise as an indicator of vascular health. The underlying mechanisms are however not fully understood. We have found, in in vivo studies, that blood pressure has a strong relation to the antegrade longitudinal displacement in early systole. Further, we have identified that a tapered geometry and the intramural friction in-between two parts of a vessel wall ...
