Abstract:
ObjectiveTo explore the value of MRI ovarian-adnexal reporting and data system （O-RADS MRI） in differentiating benign and malignant ovarian-adnexal masses.MethodsTotally 146 patients （202 masses） with ovarian-adnexal lesions who underwent pelvic examination at 3.0 T MRI according to standardized scan protocol of O-RADS MRI and were pathologically confirmed in The First Affiliated Hospital of Sun Yat-sen University between January 2020 and February 2022 were retrospectively analyzed. Two radiologists classified the ovarian-adnexal masses as risk levels 1~5 according to O-RADS MRI and evaluated their consistency by Cohen’s kappa. Using pathological findings as the gold standard， the detection yield of malignant lesions with O-RADS MRI classification was analyzed. Sensitivity， specificity， accuracy， and the area under the receiver operating characteristic curve were calculated （cutoff for malignancy， score ≥ 4）.ResultsOf 202 masses， 62 （30.7%） were malignant， 140 （69.3%） were benign. The two radiologists presented good agreement in O-RADS MRI classification of ovarian adnexal masses （Kappa=0.932）. The malignancy rates of masses with scores of 1， 2， 3， 4 and 5 were 0%， 0%， 7.7%， 95%， 97.6%， respectively. Sensitivity， specificity， accuracy， and the area under the receiver operating characteristic curve were 96.8% （60/62）， 98.6% （138/140）， 98.0% （198/202）， 0.977.ConclusionsO-RADS MRI yields high diagnostic efficiency for benign and malignant ovarian adnexal masses and its widespread implementation will improve communication between radiologists and clinicians， and facilitate optimal patient management. Therefore， O-RADS MRI warrants widespread use in clinical setting.
