Abstract：Objective To analyze the application value of Ovarian-Adnexal Reporting and Data System Magnetic Resonance Imaging(O-RADS MRI)in the diagnosis of benign and malignant adnexal tumors.Methods We conducted a retrospective analy-sis of the clinical and MRI data of 130 patients with adnexal tumors who were diagnosed and treated in our hospital,assessed ma-lignancy risk for each mass according to O-RADS risk stratification criteria.Using biopsy results as the"gold standard",we plot-ted the receiver operating characteristic(ROC)curve and calculated the diagnostic performance of magnetic resonance O-RADS.Results Among 130 cases of adnexal tumors,36 cases were malignant and 94 cases were benign in pathological bi-opsy;O-RADS 3,4,5 points were 28,18,and 20,respectively,and the malignant rates were 10.7%,83.3%,and 90.0%,re-spectively;O-RADS 1,2points were 6,58,and the pathology was benign;The area under the ROC curve was 0.964,95%CI:0.933 to 0.994;The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of O-RADS MRI score for the diagnosis of adnexal tumors were 91.7%,94.7%,86.8%,96.7%,and 93.9%,respectively.Conclusions O-RADS MRI score has high value in the diagnosis of benign and malignant adnexal tumors,which has a positive effect on the se-lection of clinical diagnosis and treatment programs.
