Female breasts, made of glandular, adipose, and connective tissue, are hormone-sensitive organs that undergo changes along with the menstrual cycle and during pregnancy. Breasts may be affected by various diseases, in which different imaging methods are important to arrive at the correct diagnosis and management. Mammography is used for breast cancer screening and diagnostic evaluation of various breast-related symptoms. Ultrasonography is rarely used for screening, but it is typically used for diagnostic workup and during procedures (e.g., breast biopsy). MRI of the breasts is used as a supplementary screening tool for those at high risk for developing breast cancer. Additionally, in individuals with breast implants, inconclusive mammographic and/or breast ultrasound findings, and diagnosed breast cancer needing evaluation pretreatment and posttreatment, MRI is an important breast radiologic tool.
