In addition it showed high sensitivity (90%), specificity (99%), PPV (92.2%), and NPV (99%) for detection of submucous myomas.18 The false positive rate for small polyps, which was 14% in our study, is high but this can be offset by other obvious advantages that saline contrast sonography has over laparoscopy and hysteroscopy.
