1. A color Doppler ultrasound diagnostic imaging method that provides blood flow parameters for diagnosing a detected mass, said method comprising the steps of: selecting a region of interest encompassing said mass; transmitting ultrasound signals along a plurality of beams traversing said selected region of interest; determining a plurality of point locations to define gated sections along each of said plurality of beams where said beams traverse blood vessels; applying a train of Doppler pulses along each of said beams individually during a complete heart cycle, then applying a train of Doppler pulses to a subsequent beam, said pulses to be transmitted to said blood vessels at said point locations to impinge on blood in said blood vessels; receiving spectral Doppler signals from said blood in said blood vessels at said point locations; and converting said spectral Doppler signals to a selected blood flow parameter.
