Women with locally advanced breast cancer are not at higher risk for contralateral synchronous breast cancer.

Breast magnetic resonance imaging (MRI) may provide a more accurate assessment of synchronous contralateral breast cancer in select cohorts of patients. The utility of this imaging technique for detecting synchronous contralateral breast cancers in patients with locally advanced breast cancer (LABC) has not previously been described. We report our experience in assessing contralateral disease in a cohort of women with LABC who had clinical assessment, mammography, ultrasound, and MRI prior to neo-adjuvant therapy.

MR imaging-guided breast localization system with medial or lateral access.

Purpose: To evaluate the degree of error of the authors' magnetic resonance (MR) imaging-guided needle localization system for biopsy of suspicious lesions visualized only with MR imaging, by using both prospectively recorded and retrospectively reviewed data, including MR imaging lesion coordinates as the reference standard, and to determine whether any lesion or breast characteristics affect this error.

Materials And Methods: Institutional review board approval, along with informed consent, was obtained as directed by the board. In 31 patients (age range, 34-64 years; mean age, 54.
