[Abstract] The differential diagnosis between benign and malignant ovarian adnexal masses has a major impact on gynaecological management strategies and patient outcomes. Although ultrasound can correctly classify most ovarian adnexal lesions, 10%-30% of ovarian adnexal lesions can not be clearly diagnosed by ultrasound. MRI can provide more accurate diagnosis for ultrasonic uncertain lesions, thus improving the clinical management and prognosis of patients. In 2022, the American Academy of Radiology (ACR) released the guidelines of the Ovarian-Adnexal Reporting and Data System (O-RADS) MRI risk stratification system, which is used to accurately evaluate ovarian accessory lesions. However, as a novel approach, this risk stratification system presents challenges: a standardized MRI protocol as well as specialized perfusion curve analysis software need to be developed, in addition, specialized training of radiologists may be necessary for the clinical use of O-RADS MRI. Further prospective cohort studies are needed in the future to develop clinical management recommendations for each O-RADS MRI risk category. Currently, there is a lack of a systematic summary of the research progress related to O-RADS MRI, and in this review, we will summarize the research progress on O-RADS MRI in terms of its proposal, clinical significance and application value, relevant research hot spots, deficiencies and future directions, in order to help radiologists apply this risk stratification system in their clinical work and try to find potential boosting points for this risk stratification system, which in turn continuously increases its differential diagnostic efficacy.
