[Ultrasound examination of the breast. Experience with a high resolution 'real-time'-scanner (author's transl)]

A new high resolution real-time ultrasound scanner for diagnosis of the breast is presented. The scanner is designed for the examination of peripheral blood vessels, all superficial soft-tissue organs, such as the thyroid, breast, salivary glands, testes as for well as pediatric examinations. It is a mechanical linear scanner with electronic and mechanical transducer focusing. Its high resolution as such and also the sonographic appearance of benign and malignant breast lesions are demonstrated, general problems of ultrasound examinations of the breast are discussed. The equipment under evaluation is of considerable value in the differentiation of palpable or otherwise localised breast tumors. It is less useful for a general application in the screening for breast cancer.
