Unfertilized chicken eggs as a biological phantom for prostate imaging using magnetic resonance elastography and diffusion-weighted imaging.

Magnetic resonance elastography (MRE) allows noninvasive measurement of tissue viscoelasticity and is increasingly applied to characterize soft tissue biomechanics. This study investigates unfertilized chicken eggs as a biologically significant and cost-effective prostate phantom for combined MRE and diffusion-weighted...

Longitudinal Multifrequency MR Elastography Reveals Biomechanical Signatures of Progression in a Translational Liver Tumor Model

ABSTRACT Conventional magnetic resonance imaging (MRI) often detects liver tumors after morphologic and vascular changes become apparent, whereas biomechanical alterations may precede visible tumor formation. Here, we evaluate multifrequency magnetic resonance elastography (mMRE)‐derived shear wave speed (SWS) and phas...

Magnetic resonance elastography of brain tumors.

The literature reviewed here increasingly supports reduced tissue fluidity and increased mechanical heterogeneity as biomechanical hallmarks of brain tumor aggressiveness.

Contractile and Hemodynamic Modulation of Skeletal Muscle Viscoelasticity Quantified In Vivo by Ultrasound Time-Harmonic Elastography.

Skeletal muscle is a living, perfused soft tissue whose viscoelastic behavior is shaped by both voluntary contraction and hemodynamic state. However, the independent and superimposed contributions of contractile loading and blood flow restriction (BFR) have not been quantified simultaneously in real time. Twenty-six he...

Toward self-contained cardiac magnetic resonance elastography: Deep learning-based segmentation of the left ventricular myocardium.

Cardiac MRE data alone demonstrated the feasibility of accurate LV myocardium segmentation, with nnU-Net and MedSAM both reaching inter-reader-level performance and represent a step toward a self-contained cardiac MRE workflow.
