[The ultrasound examination of salivary gland]

The results obtained after the examination of 107 ultrasound cases of changed salivary glands were presented. The characteristic features for changes most often appearing in salivary glands were presented. In case of tumours and cysts the diagnosis was formed on the basis of the ultrasound character of the change (low homogenas, density in cysts, higher density, non homogenous character in tumours), the degree of separation from the surrounding tissue (clear capsule in cyst and benign tumours, lack of capsule, indistinctive image in change of malignant character, in case of infiltration of surrounding tissues). The diagnosis of inflammation was made depending on the character of the change of the parenchyma of salivary gland--the increase of the gland with the lowering of density characteristic for acute inflammation, the reduction of size, increased sonographic density, enlarged leading out (duct), the echo of concrement is characteristic together with the accompanying acoustic shade for bigger concrements.
