Using T2-Weighted Sequences to More Accurately Characterize Breast Masses Seen on MRI

T2-weighted images are a valuable component of the MRI evaluation of breast masses. Edema, hemorrhage, mucus, and cystic fluid within a lesion are clearly depicted on T2-weighted sequences. In general, masses that have high signal intensity on T2-weighted images are benign; however, breast imagers must be aware of such important exceptions as mucinous carcinoma and necrotic tumors.
