Table 3 Comparison of various combinations of three diagnostic methods 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 methods Sensitivity (%) Specificity (%) PPV (%) NPV (%) Accuracy (%)
Mammography + MR mammography 98.9* 90.5 88.4 99.1* 94.1
Sonography + MR mammography 98.9* 93.3 91.5 99.2* 95.7
Mammography + sonography 94.6 92.1 89.7 95.9 93.2
All three methods combined 99.4 95.3 93.9 99.6 97.0†‡
  1. * P < 0.05, versus mammography and sonography; P < 0.005, versus mammography and sonography; P < 0.05, versus MR mammography and mammography. NPV, negative predictive value; PPV, positive predictive value.
