Shear Wave Elastography (SWE) is a cutting-edge ultrasound-based imaging modality that provides real-time, quantitative assessment of tissue stiffness. By utilizing acoustic radiation force to generate transverse shear waves, SWE measures the speed of wave propagation, which correlates directly with tissue elasticity. This technique has shown significant clinical value in differentiating benign from malignant lesions, particularly in the liver, breast, thyroid, and musculoskeletal tissues. Unlike strain elastography, SWE offers operator-independent, reproducible results with measurable stiffness values in kilopascals. The integration of SWE into routine diagnostic workflows enhances diagnostic accuracy, reduces the need for invasive procedures, and supports earlier disease detection. Despite some limitations, such as depth sensitivity and motion artifacts, SWE continues to gain prominence as a reliable tool in non-invasive tissue characterization.
