[Breast sonography with high-frequency short-focusing transducers].

Since 1984 two high-frequency short-focussed linear transducers have been used for breast sonography at Innsbruck University Gynaecological Clinic. In the study reported here 121 patients with pathologic change in the breast were examined. A significant improvement in diagnosis was achieved: on the one hand because of the improved resolution and distinction of the lesions, and on the other because of the manageability of the transducers and the individually adjustable breast compression. Both perforation of the physiological mammary strata as well as clearly distinguishable tumor ends without echoproof halos were considered reliable indicators of the malignancy of the respective changes.
