Contrast-enhanced breast MAGNETIC resonance imaging (MRI) has been shown to have very high sensitivity in the detection of breast cancer, with a significant increase in the number of breast MR examination. In this study, the numerous morphologic and kinetic features have been described and reported for characterizing benign and malignant lesion. These features result in lack of appropriate descrip-tion of the lesions, frequent problems of communication with the referring physicians, or difficulties for comparing different MR studies in some patients. As with mammography and ultrasound, a breast MRI reporting system is used for describing abnormal MR findings, resulting in an standardized description, an organized report with a final assessment of the lesion.This article reviews the interpretation criteria in breast MR imaging based on breast imaging and reporting DATA system (BIRADS).Interesting and practical cases will also be present in this article in order to become familiar with BIRADS MRI.
