Current status of MR-Mammography : Technique and findings

Abstract

In our hospital, magnetic resonance imaging of the breast (MR-mammography, MRM, 0.5T) was performed using T1-weighted gradient echo with fat suppression and magnetization transfer contrast before and after infusion of Gd-DTPA using key hole imaging which substituted localized dynamic study. In our experience, MRM is useful for diagnosis of difficult cases and surgical planning for breast preservation because of its high tumor-gland contrast and clear three-dimensional demonstration. MRM is also useful for determining the response to preoperative chemotherapy. However, tumor visibility depends mainly on the nature of the background breast glands.
