Technology development in data processing in ultrasonography let new imaging method feasible. New method of imaging is elastography (elastosonography, ultrasonographic elastography). It relays on the presumption that pathologically changed tissues have different elasticity and change their shape in different way than health tissue. Elastography is used in lesions in alimentary tract diagnostics. Sensitivity and specificity in malignant lesions differentiation is 85% and 90%. In elastography there is used conventional ultrasonography device that is equipped with additional transformator that is located in probe. Examination is performed with multiple pressing the organ. Imaging is acquired in real-time regime they are colour-coded and they are created during compression. As a result of computer analysis images are generated in two colours. On the basis of character of normal and increased rigidity images were classified in five point scale from one to five. Indication to elastography is suspicion of malignant lesions in traditional ultrasonography and monitoring of liver cirrhosis and fibrosis. More trials are required to evaluate this method more reliably. Then it could be recommended for everyday clinical use.
