Malignant tumours can be differentiated from the benign ones by their vascular blood supply. We employed three methods to analyse the blood flow: the angiodynograph, the duplex system, and the continuous-wave Doppler method, and measured the blood flow in 151 patients on the preoperative day. Histology revealed a malignoma in 92 cases and a benign tumour in 59 cases. It was found, that in more than 90% of the malignomas, a high blood flow was identified in or around the tumour by means of the colour method (angiodynography), which could be quantified by the pulsed-wave Doppler. A significantly lower blood flow was evident in the benign tumours with a markedly increased resistance index (by 80%) established by means of the pulsed-wave Doppler. Continuous-wave (CW) Doppler showed a significantly higher blood flow with almost all malignomas in the entire breast, than was the case with benign changes. Our studies showed, that the enhanced blood flow in and around malignant tumours can be visualised by means of update technology, angiodynography being particularly suitable for demonstrating the flow by the B-mode. Quantification, however, is, at present, only possible by employing the duplex method with pulsed-wave Doppler. CW Doppler is suitable only for blood flow diagnosis of the entire organ, but it requires great precision of working method and is time consuming; tumour blood flow cannot be visualised on-target by this method.
