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.
手术前，我们研究了59个乳腺肿瘤（35个恶性和24个良性）及其周围的血流情况，并研究了其与组织学的相关性。最具决定性的因素是舒张末期最大频率B（概率大于z值的幅度=0.0009）和平均频率F均值（概率大于z值的幅度=0.0017）。收缩期最大频率A、阻力指数Ri、舒张角W和搏动指数Pi在恶性和良性组织学类型之间的差异不太显著。在一项回顾性调查中，我们试图通过多普勒结果来确认最终的组织学类型。在这方面，我们在17.14%的恶性病例和33.33%的良性肿瘤病例中未能成功。
