[Analysis of a method for Doppler study of the female breast].

Besides characteristic morphological differences, carcinomas of the breast show remarkable changes of vascularity, which are essential for their enhanced metabolism. High-frequency CW Doppler allows to investigate normal and pathological vascularisation in the breast. In our basic study we examined 200 patients, 37 with breast malignancies (6 non-palpable lesions). 33 of the carcinomas showed pathological vascularisation. In an extended examination procedure we investigated also normal breast vascularisation and compared it with blood flow in lesions. We developed therefrom an easy and rational method which allows physiological blood flow measurements as well as a differentiation of breast lesions within a few minutes' time.
