5.1\ Scanning Method

Transverse or longitudinal scan around nipple

5.2\ Section Structures

Skin, subcutaneous fat, mammary gland, and mammary ducts 1–6 duct

5.3\ Clinical Application Value

To observe whether there is a milk retention cyst or irregular dilated duct. The sonographic appearance of the milk retention cyst is round or oval anechoic, and the wall is smooth and thin; punctate hypoecho or hyperecho content can be seen in it. With a vibration of probe or a change in body position, its content is slow flow. It should be identified with breast abscess. An irregular expansion of breast duct with the concentration of the milk needs to be discriminated with the ductal papilloma (or cancer).

6.1\ Scanning Method

Patient lies on the back. Patient could lie on the contralateral side when examining the outer quadrant. Continuously take longitudinal and transverse scanning or radial scanning along the nipple. The breast duct can be better displayed by the radial scanning.

6.2\ Section Structures

From superficial to deep in order, skin, mammary gland, mammary ducts, and blood vessels can be seen.

6.3\ Clinical Application Value

To understand the characteristics of breast ultrasound during lactation. During lactation, mam-

mary gland thickening, and fat reduction, subcutaneous fat and behind fat of glands obviously become thin or disappear. Milk secretion continuous, as well as storage and filling of mammary duct. The structure of the mammary gland during lactation is dense, showed hyperecho or hypoecho. Because the acoustic density of milk is higher than that of water, the fat droplets in the milk have shown a hyperecho; the whole breast is cloud and mist-like. In addition, because echo of milk is high, making mammary duct in periphery is unclear, and thickened duct in central area is clear. To observe whether there is a mass in the breast. If the water is gradually absorbed in the cystic cavity of the milk retention cyst, formed hard mass is similar to solid mass; this should be differentiated with fibro adenoma and breast cancer.
