Patients

We retrospectively reviewed the clinical data and magnetic resonance images (MRI) of 111 consecutive patients who were referred for MRI-guided breast biopsy between May 2009 and April 2019. We excluded 37 patients who lacked follow-up images for more than 2 years. Thus, 74 patients (74 lesions) were included in this study. MRI was the only imaging modality used in 14 patients who received interstitial foreign body injections. All other patients underwent mammography and breast US scans before a breast MRI, and suspicious lesions detected on MRI tested negative on both mammography and US scans; re-evaluation of mammography and second-look US scans targeting the MRI-detected lesions were also negative.
