Table 3 Diagnostic performance of MRI features for characterizing ovarian CCC

From: Magnetic resonance imaging for distinguishing ovarian clear cell carcinoma from high-grade serous carcinoma

MRI features Sensitivity (%) Specificity (%) Accuracy (%) PPV (%) NPV (%) PLR
Unilocular cystic mass 90 (26/29) 89 (24/31) 83 (50/60) 79 (26/33) 89 (24/27) 8.18
Oval shape 75 (30/40) 82 (51/62) 79 (81/102) 73 (30/41) 84 (51/61) 4.16
Papillary projections (≥3 cm) 85 (24/28) 71 (21/31) 76 (46/59) 71 (24/34) 76 (21/25) 2.93
T1-hyperintense cystic component 62 (18/29) 84 (26/31) 73 (44/60) 78 (18/23) 70 (26/37) 3.88
  1. Data in parentheses are the numbers of masses; PPV positive predictive value, NPV negative predictive value, PLR positive likelihood ratio
