From: Diagnostic efficacy of gel infusion sonography in post-menopausal bleeding
Real-time imaging | Sensitivity % | Specificity % | PPV % | NPV % | Accuracy % |
|---|---|---|---|---|---|
Polyp | 92 (88–97) | 91.3 (86–93) | 90 (88–91) | 97.7 (88–99) | 91.5 (86–97) |
Hyperplasia | 77 (71–79) | 65.9 (60–67) | 68 (58–68) | 79 (78–87) | 75 (69–82) |
Cancer | 91.4 (89–93) | 93 (88–97) | 86 (82–93) | 95.8 (83–99) | 92.7 (88–98) |
No endometrial abnormality | 90.3 (89–93) |
