Atlas of breast magnetic resonance imaging

Magnetic resonance imaging (MRI) of the breast has become important not only for assessing the extent of breast cancer for breast-conserving surgery but also for the evaluation and diagnosis of other benign and malignant pathologies. We radiologists therefore need to know the appropriate indications for performing breast MRI and understand the MRI features of breast disease. We herein review and discuss the application of current pulse sequences and the imaging strategies for MRI of breast pathologies. We will illustrate the MRI features of various breast pathologies including malignant tumors such as invasive and noninvasive ductal carcinoma, special types of invasive carcinoma (mucinous, apocrine, lobular carcinoma, spindle cell carcinoma, and so on), inflammatory carcinoma, semimalignant tumor (phyllodes tumor), benign tumors (fibroadenoma, intraductal and intracystic papilloma), inflammatory conditions, and postsurgical changes. We will also demonstrate three-dimensional fusion images of MR ductography and breast MRI of patients with nipple discharge.
