[Ultrasonographic elastography in alimentary tract lesions diagnostics].

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.

[Conditions and limits of radiological examinations of the digestive tract].

The rising incidence of alimentary tract diseases forces imaging metod development. Developing radiologic diagnostics changed imaging methods role and increased quality demand. X-ray based methods are still used in diagnosing many illnesses.
