Popis: Introduction: In 2019-20, the American College of Radiology (ACR) introduced Ovarian-Adnexal Reporting and Data System Magnetic Resonance Imaging (O-RADS MRI). Application of the O-RADS MRI in routine clinical practice can increase lesion characterisation accuracy, promote better interdisciplinary communication, and help in personalised patient management of adnexal masses. Aim: To assess the diagnostic performance of the ACR O-RADS MRI scoring system for the predicting malignancy in adnexal mass in routine clinical radiology practice by using histology/imaging findings during a minimum 4 month follow-up as the reference standard. Materials and Methods: This single-center prospective cohort study was conducted in Jorhat Medical College, Assam, on 42 patients with 46 adnexal masses who underwent MRI between April 2020 to June 2021 were assessed. The ACR O-RADS Magnetic Resonance (MR) scores were assigned using the MRI protocol with a dynamic study. Sensitivity, specificity, positive and negative predictive values along with the area under the Receiver Operating Characteristic (ROC) curve was calculated (cut-off score ≥4 was considered malignancy,). Histopathologic diagnosis or >4 months follow-up imaging findings were the reference standard used. Logistic regression analysis of MRI parameters used in identifying malignant masses were assessed. Statistical analysis was done using 95% Confidence Intervals (CI). The p-values
