title: False-negative results of breast MR computer-aided evaluation in patients with breast cancer: correlation with clinicopathologic and radiologic factors.
abstract: OBJECTIVE
  To investigate clinicopathologic and radiologic factors associated with false-negative results of magnetic resonance computer aided evaluation (MR-CAE) of breast MR imaging (MRI) in breast cancer patients.
  
  
  METHODS
  A total of 135 breast cancer patients who underwent preoperative breast MR-CAE were included. False-negative and true-positive MR-CAE results were compared in terms of clinicopathologic and radiologic features. Univariate and multivariate analyses were used to evaluate independent factors associated with false-negative results.
  
  
  RESULTS
  Six of 135 cancer patients (4.4%) were false negative on MRI.
  
  
  CONCLUSIONS
  Breast cancer with false-negative results on MR-CAE was classified as a lower BI-RADS category on breast ultrasound than true-positive results on MR-CAE.
