[Computer-assisted quantitative evaluation method of color Doppler images in tumor diagnosis].
METHODS
This article reviews methods for objective color Doppler quantification. The principles, limitations and reliability of an objective computer-assisted method of quantitative color Doppler image analysis are described and its role in the assessment of tumor vascularization with regard to differential diagnosis, prognosis and monitoring of therapy effects is evaluated.


CONCLUSIONS
Color Doppler images are quantitatively characterized by the percentage of color pixels in a selected region of interest and the flow velocities corresponding to the encoding colors.
