Ultrasound devices and methodologies have been continuously evolving and becoming more important as tools in diagnostic medicine. Recently a new ultrasound diagnostic technique has been developed. Named sonoelastography, the technique enables evaluation of tissue elasticity and is based on differences in stiffness (hardness, compressibility, elasticity) of pathological changes and normal adjacent tissue. Sonoelastography (SE) is also known as Real-time tissue elastography (RTE), Real-time

... astography (RTSE), Tissue type imaging (TTI) and Ultrasound Strain Imaging Technology. It has been found useful in many medicine elds and adopted readily by clinicians of different specialties. It gives more information than conventional ultrasound in evaluation of tumors, liver disease, skeletal muscles, rheumatoid nodules and other pathological changes. This review covers the basics of elastography, its applications, instruments, techniques, the scoring system and the indications for elastography.
