Sažetak
Shear-wave elastography (SWE) uses ultrasound to estimate the stiffness of tissues by measuring the degree of distortion and produces dal-time quantative color-coded map od local tissue elasticity. No manual compression is required. Pulses are successively focused at different depths in tissue at supersonic speed. Shear wave propagation is captured with plane waves. Shear wave propagation speed relates directly to the local elasticity of tissue and can be measured in kilopascals. So called "Q-Box" quantification tool accurately measures, in real time, true tissue elasticity in kilopascals by placing a region of interest (ROI) in the desired area. Multiple areas of interest can be compared, and ratios of stiff between these areas measured (E-ratio). The aim of the study was to analyze and compare SWE features of normal thyroid gland, and of benign and malignant thyroid nodules.
