Final answer:
In breast ultrasound, hyperechoic structures are those that reflect more sound waves, appearing brighter on the imagery. Normal breast structures with hyperechoic appearance include Cooper's ligaments and the interface between fat and glandular tissues, while abnormal hyperechoic findings could indicate calcifications or fibroadenomas.
Step-by-step explanation:
In medical imaging, particularly in ultrasound, hyperechoic refers to tissues that reflect more sound waves, resulting in a brighter image on the screen. Within the context of breast structures, hyperechoic features can refer to certain normal and abnormal findings.
Normal breast structures that are typically hyperechoic include Cooper's ligaments, which are fibrous connective tissues providing structural support to the breast, and the interface between adipose tissue and the glandular tissues of the breast, where there is a stark difference in density.
Abnormal hyperechoic findings might include calcifications or fibroadenomas, which are benign breast tumors consisting of glandular and fibrous tissues that reflect sound waves more readily than the surrounding tissues.
