Diagnostic accuracy of resection margin in specimen radiography: digital breast tomosynthesis versus full-field digital mammography.

Objective: We investigated the accuracy of digital breast tomosynthesis compared to full-field digital mammography for evaluating tumor-free resection margins in the intraoperative specimen during breast-conserving surgery, reducing re-excision rates.

Materials And Methods: In total, 170 patients, with proven breast cancer and eligible for breast-conserving surgery, were enrolled. Intraoperative specimens underwent digital mammography and digital breast tomosynthesis.
