Question

which of the following terms represents slow flow within vessels?
power doppler
intensity
attenuation
echogenicity

Explanation:

Power Doppler is a technique that is sensitive to slow - flow within vessels. Intensity refers to the strength of a signal. Attenuation is the reduction in the amplitude of a wave as it propagates. Echogenicity is related to the ability of a tissue to produce echoes.

Answer:
