title: [Color Doppler flow data of breast tumors].
abstract: The recent development of high-quality colour Doppler instruments allows flow detection in small vessels below the resolution of B-mode imaging. Therefore, Doppler is now frequently used for flow detection in tumours. For breast examinations, CW Doppler has been in use for many years, which allows a sufficient definition of diagnostic criteria. Nevertheless, it is surprising that new studies using colour Doppler try to define different diagnostic criteria. To characterise the vascularity of breast lesions by colour Doppler we investigated 127 symptomatic patients. In 54 carcinomas the average flow velocity was 32 cm/s and 12.6 cm/s in 73 benign conditions (p > 0.0001). Total tumour vascularisation was characterised by a new parameter: the sum of all flow velocities in all tumour vessels. In carcinomas the mean total flow as 197.9 cm/s, and 52.7 cm/s in benign pathologies (p > 0.0001). Mean RI (resistance index) and PI (pulsatility index) were calculated to describe the flow profiles. The wide variation did not allow for a differentiation between benign and malignant lesions.
