[Differential breast diagnosis using CW-Doppler ultrasound].

There is no method that allows satisfactory differentiation between benign and malignant breast lesions. We were able to differentiate 94% of palpable malignant tumours with CW-doppler ultrasound, which helps to increase the efficiency of clinical examinations, breast sonography and mammography. Two hundred patients were examined with an 8 MHz CW-doppler probe. The symmetry of arterial vessels and flow velocity in normal breasts is very high. Carcinomas appear as areas with localized flow increase. Only in two normal patients was a minimal focus of two arteries found.
