Breast ultrasound examination, the correct depth from the surface of skin, subcutaneous fatty tissue, glandular and fibrous layer, fat layer, composed of muscle fascia and muscle layers. Hyperechoic in U.S. is skin, breast thickness increases closer to the beginning. Normal breast skin thickness does not exceed two to three millimeters. Subcutaneous fat layer in the form of a band is hypoechoic ovoid configuration, compared to the surrounding glandular tissue, hypoechoic, echogenic a nidus is formed by the connective tissue of the plant. The thickness of this band, the patient will vary according to age. Young women with dense breasts, and the subcutaneous fat layer is so thin to be seen. Breast tissue, a pattern usually shows a homogeneous echogenity. However, increases fatty involution increases, hypoechoic areas.
Glandular structure, occupies a large portion of breast glandının. Higher than the upper outer quadrant and axillary region. With connective tissue are seen as heterogeneous. Hypoechoic layer of fat and muscle layer. Ribs are hypoechoic image in the field, creates the posterior parts of the acoustic shadow. Ducts of the breast milk, breast showing convergence toward the beginning and the expanding diameter of 1-8 mm is seen as anechoic tubular structures. The nipple is moderately echogenic, acoustic shadowing is seen on the posterior. Physiological characters and the axillary lymph nodes IMLN long, ovoid hypoechoic structures in configuration and are usually seen as echogenic fat.
