Background
-Ultrasound is the most commonly used imaging tool for the assessment of ovarian and other adnexal lesions. -The discrepancy in terminology leads to inconsistent reporting of US findings, which leads to substantial differences in management. -A standardized lexicon for ovarian lesions is presented. Applying this lexicon for risk stratification classification improves communication with clinicians, eliminating ambiguity in the reports, and facilitating consistent follow-up and management.

Educational Goals / Teaching Points
-Describe all ACR O-RADS US lexicon terms that were agreed on by the ACR O-RADS committee. Familiarize imagers with the ACR risk stratification, classification, and recommended management.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
1-ACR O-RADS Definitions: Lesion, Physiologic, cyst, solid, unilocular or multilocular cyst, septation, papillary projections. 2-Description of the O-Rads categories with the illustration of US findings in each.

Conclusion
-O-RADS risk stratification and management comprise an approach offering consistent interpretation and eliminating ambiguity in reports, in addition to offering management guidance.
