Magnetic resonance elastography (MRE) is a phase contrast–based MRI technique that can
measure displacement due to propagating mechanical waves, from which material …

The physical microenvironment of cancer is characterized by elevated stiffness and tissue
pressure, the main component of which is the interstitial fluid pressure (IFP). Elevated IFP is …

MRI-based biomechanical studies can provide a deep understanding of the mechanisms
governing liver function, its mechanical performance but also liver diseases. In addition …

Intrinsic actuation MR elastography (IA-MRE) exploits natural pulsations of the brain as a
motion source to estimate mechanical property maps. The low frequency motion of IA-MRE …

The solid and fluid pressures of tumours are often elevated relative to surrounding tissue.
This increased pressure is known to correlate with decreased treatment efficacy and …

Background Elevated tumor tissue interstitial fluid pressure (IFP) is an adverse
biomechanical biomarker that predicts poor therapy response and an aggressive …

Magnetic Resonance Elastography allows noninvasive visualization of tissue mechanical
properties by measuring the displacements resulting from applied stresses, and fitting a …

This work focuses on the numerical solution of the dynamics of a poroelastic material in the
frequency domain. We provide a detailed stability analysis based on the application of the …

Purpose Biological soft tissues often have a porous architecture comprising fluid and solid
compartments. Upon displacement through physiological or externally induced motion, the …

Magnetic resonance elastography is a motion-sensitive image modality that allows to
measure in vivo tissue displacement fields in response to mechanical excitations. This paper …
