Specimen radiography in confirmation of MRI-guided needle localization and surgical excision of breast lesions.

Objective: Confirmation of lesion retrieval after MRI-guided needle localization and surgical excision of breast lesions are difficult because the targeted lesion is not enhanced ex vivo. The aim of this study was to determine the feasibility of using specimen radiography to verify lesion removal after MRI-guided needle localization and surgical excision.

Conclusion: To our knowledge, our study was the first to examine the use of specimen radiography in the localization and excision of breast lesions.

BI-RADS-MRI: a primer.

Objective: Variations in breast MRI techniques and descriptions of morphologic findings led to the development of a breast MRI lexicon. This lexicon, the American College of Radiology's BI-RADS-MRI, includes terminology for describing lesion architecture and enhancement characteristics. We show the use of these descriptors on breast MR images obtained at our institution.
