title: Follow-up outcomes after benign concordant MRI-guided breast biopsy.
abstract: OBJECTIVE
  To evaluate outcomes of benign concordant magnetic resonance imaging (MRI)-guided breast biopsy.
  
  
  METHODS
  We retrospectively reviewed 611 consecutive MRI-guided breast core biopsies at our institution from 2005 to 2012. Benign concordant cases with MRI follow-up constituted the study group. Lesion appearance on follow-up MRI was assessed and the false-negative rate was calculated.
  
  
  RESULTS
  Eighty-four lesions in 68 women underwent benign concordant MRI-guided biopsy with subsequent MRI follow-up. Mean time to first follow-up MRI was 10.5 months. Two false negatives were identified on follow-up at 8 and 26 months.
  
  
  CONCLUSIONS
  We report a false-negative rate of MRI-guided breast biopsy of 2.4%.
