[New aspects in ultrasound mammography (author's transl)].

We report about 239 ultrasound examinations of the breast using a new water-tank scanner (U.I.Octoson, Ausonics, Sydney, Australia). A very good tissue differentiation of the brease is caused by a special technique and a high resolution. Beside benign results, typical findings in 49 malignancies are demonstrated ("shadowing", "christmastree-sign") and its value discussed. All ultrasound examinations are correlated to X-ray mammography, thermography, needle-biopsy and patho-histology.
