Objective To compare the diagnostic value of contrast-enhanced ultrasound （CEUS） and enhanced magnetic resonance imaging （MRI） in indeterminate pelvic masses. Methods CEUS and MRI were performed on 46 cases of sonographically indeterminate pelvic masses according to International Ovarian Tumor Analysis （IOTA） simple rules. Two independent sonographers and two radiologists reviewed the images before and after combining with medical history and serum tumor markers, respectively. The results of CEUS and MRI were compared with pathologic findings （n = 43） or follow-up data after clinical treatment （n = 3） as gold standard. The diagnostic values of CEUS and MRI before and after combining with medical history and tumor markers were compared. Results The diagnostic accuracy of CEUS in indeterminate pelvic masses was 67.4% without combining with medical history and tumor markers, which was lower than 80.4% of MRI. There was a statistical significance （P < 0.05）. However, there was no statistical significance between them after combining with tumor markers and/or medical history （both P > 0.05）. The accuracy of CEUS combined with medical history and tumor markers in diagnosing pelvic masses was 91.3%, which was statistically different from CEUS without considering any medical histories （P < 0.05）. Conclusion When combining with medical history and tumor markers, CEUS yields an equivalent diagnostic accuracy in differentiating malignant from benign pelvic masses compared with MRI. CEUS has high clinical value for diagnosing indeterminate pelvic masses.
