[Ultrasonography in the diagnosis of metastases of cancer of the large intestine to the liver].

Ultrasonography using a method of sectional and contact scanning is a valuable method of diagnosis of metastatic liver involvement in colon cancer. The diagnostic accuracy of the method is 95.6%. It has been noted that metastases of the same colon tumor type have different echostructure which depends on a period of disease and size of metastases. The author has defined 6 types of changes in the echostructure of metastases. In individual cases in a certain structure of metastasis changes in the liver parenchyma at ultrasonography were undetectable.
