title: [Doppler ultrasound differentiation of benign and malignant breast tumors].
abstract: Before surgery we studied the blood flow in and around 59 breast tumours (35 malignant and 24 benign) and investigated a correlation with the histology. The most decisive factors were the maximum end-diastolic frequency B (probability greater than magnitude of z = 0.0009) and the mean frequency F mean (probability greater than magnitude of z = 0.0017). The maximum systolic frequency A, the resistance index Ri, the diastolic angle W and the pulsatility index Pi showed less significant differences between malignant and benign histological types. In a retrospective survey, we tried to confirm the definitive histology by our Doppler results. In this, we failed in 17.14%--of malignant cases and in 33.33% in the cases of benign tumours.
