Ultrasound Imaging and Elastography

Ultrasound elastography measures how stiff or compliant biological tissues are by tracking how they deform in response to mechanical forces, producing spatial maps of elasticity that conventional imaging cannot provide. Because many diseases—including cancers, fibrotic liver conditions, and musculoskeletal injuries—alter tissue stiffness before they cause visible structural changes, these techniques can improve diagnosis and reduce the need for invasive biopsies. Methods range from shear wave imaging, which uses acoustic radiation force to generate measurable wave propagation through tissue, to magnetic resonance elastography, which extends similar principles with higher spatial resolution in deeper or more complex anatomy. Active research is focused on standardizing quantitative stiffness measurements across different scanner platforms and expanding reliable clinical thresholds for conditions such as breast lesion characterization, where distinguishing benign from malignant masses remains an area of ongoing refinement.
