Fig. 5.7  Color Doppler imaging of normal breast in lactating women

7.1\ Scanning Method

Based on two-dimensional scanning, start color Doppler. The color gain is adjusted to the maximum sensitivity without noises; meanwhile the

From superficial to deep in order: the skin, mammary gland, and ectopectoralis

Reported in the literature, the more milk, the more thick blood vessels, the faster velocity, and the lower the resistance index; on the contrary, milk secretion is insufficient.
