O-RADS US Combined With MV-Flow Technique In The Benign And Malignant Diagnosis Of Adnexal Mass

Objectives: To explore the application of the Ovarian-Adnexal Reporting and Data System Ultrasound(O-RADS US)combined with MV-Flow to in the diagnosis of benign and malignant adnexal masses.Methods: A total of 112 ovarian-adnexal masses,namely,81 benign and 31 malignant masses,from 105 consecutive patients were included in the study.The O-RADS US and vascular index(VI)from MV-Flow were measured for the above masses and compared with the reference standard.Both O-RADS US and MV-Flow were tested for consistency.Results:Receiver operating characteristic curves(ROCs)were drawn for O-RADS US,MV-Flow and their combination.The combined methods had the largest area under the curve(0.955),followed by O-RADS US(0.929)and MV-Flow(0.923).In each diagnosis,the mass was considered malignant when the O-RADS US classification was 5 and VI was ≥ 7.15.With this definition,MV-Flow had the highest sensitivity(87.10%),which remained consistent sensitivity between the combined diagnostic methods and O-RADS US(83.87%).The specificity of the combined diagnostic methods(93.83%)was higher than that of MV-Flow(91.36%),and 0-RADS US had the lowest specificity(90.12%).The combined diagnostic methods had the highest coincidence rate(91.07%),and MV-Flow(90.18%)had a significantly higher coincidence rate than O-RADS US(88.39%).Regarding consistency among the different physicians,both O-RADS US and MV-Flow performed well(Former Kappa: 0.974,the latter ICC: 0.986).The same-physician MV-Flow had a high consistency(ICC: 1).Conclusions: O-RADS US and MV-Flow have good diagnostic efficacy,and their combined diagnostic efficacy is higher than that of each individually.O-RADS US and MV-Flow can further improve the diagnosis of benign and malignant ovarian-adnexal masses.
