Lactiferous ducts are typically found within which tissue on imaging?

Explanation:
Lactiferous ducts are part of the breast’s ductal system and run through the breast’s glandular (fibroglandular) tissue toward the nipple. On imaging, this breast tissue—seen on ultrasound and mammography as the fibroglandular or dense/parenchymal component—provides the environment where the ducts are located and visualized. Fatty replacement tissue, while it may surround the ducts, is less informative for ductal anatomy and can make ducts harder to see, so the ducts are typically identified within the breast tissue itself rather than in fat or other structures like lymph nodes.
