Table 2 Comparison of mammography, sonography and MR mammography for preoperative prediction of histologically confirmed invasive cancer (n = 185) or benign disease (n = 254)

From: Comparison of written reports of mammography, sonography and magnetic resonance mammography for preoperative evaluation of breast lesions, with special emphasis on magnetic resonance mammography

Diagnostic method Sensitivity (%) Specificity (%) PPV (%) NPV (%) Accuracy (%)
Mammography 83.7 68.5 67.8 84.1 77.1
Sonography 89.1 79.1*† 65.7 90.9 83.4
MR mammography 94.6*† 68.5 68.6 94.6 79.5
  1. * P < 0.005, versus MR mammography; P < 0.05, versus mammography; P < 0.05, versus sonography. NPV, negative predictive value; PPV, positive predictive value.
