Abstract: This study was to investigate the value of gynecological imaging reporting and data system (GI-RADS) combined with serum tumor markers in the differential diagnosis of benign and malignant ovarian masses. The ultrasonic imaging data of 132 patients with ovarian masses were reviewed. There were 90 patients with benign masses and 42 patients with malignant masses. the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of parallel diagnosis of GI-RADS combined with serum tumor markers were 83.33%, 74.44%, 77.27%, 60.34% and 90.54%, respectively. The sensitivity, specificity, accuracy, positive predictive value and negative predictive value of tandem method were 64.29%, 90.00%, 81.82%, 75.00% and 84.38%, respectively. GI-RADS combined with serum tumor markers has good clinical application value in the differential diagnosis of benign and malignant ovarian masses.
