Challenges to interpretation of breast MRI.

This review describes the current knowledge and challenges of lesion interpretation with MRI of the breast according to different image interpretation strategies. Particular emphasis is given to patient- and tumor-related factors that influence image interpretation. The impacts of the menstrual cycle, prior surgery, radiation therapy, and chemotherapy are summarized. Particular enhancement features of ductal carcinoma in situ (DCIS) or invasive lobular carcinoma are described. Finally, an adequate diagnosis at MRI of the breast should take into account the results of the patient's history, physical examination, and all imaging tests performed before MRI. J. Magn. Reson.
