Elastography ultrasound is a technique used to evaluate the mechanical properties of tissues by applying pressure on the probe and detecting tissue displacement through ultrasound waves. This method is currently being researched and applied in diagnosing musculoskeletal disorders. A rheumatic nodule can be visualized using both conventional (gray-scale) and elastography ultrasound. On a standard ultrasound image, the area appears relatively homogeneous, without clearly defined soft or fluid regions. However, when elastography is applied, softer areas (green, yellow, red) can be visualized, while the surrounding tissues appear stiffer (blue)
