[Sonographic studies in the differential diagnosis of thyroid diseases].

In the investigation period from May 1982 to February 1985 1,150 sonographies of the thyroid gland (B-scan) were performed, of which 240 patients underwent a fine-needle aspiration. The results of the sonography were compared with the findings of scintigraphy and the results of cytology. With the help of own investigations the indications, the advantages and limits as well as the value of sonography were demarcated under the conditions of our clinic.
