[Use of B-sonography in the diagnosis of liver diseases]

The criteria important for the sonographic judgment of the liver and the value of the sonography in the strategy of the diagnostics of liver diseases are described. Since none of the symptoms mentioned, such as size of the liver, ventral contour, lower margin of the liver, demarcability, sound conduction as well size, density and distribution of the structural reflexes, is typical for a certain disease, an approximate diagnosis or the exclusion of certain diseases is a possible only taking into consideration several symptoms and also extrahepatic, sonographically probable ones. On account of the simplicity and of the undangerousness of the examination it is obvious to use the sonography immediately after the examination and thus to organize the selection of further diagnostic measures more rational.
