- Ovarian-Adnexal Reporting and Data System (O-RADS)
Definitions
- Standardized lexicon and risk stratification tool for characterization of adnexal lesions essential for optimal patient management
- 2 arms: Ultrasound (US) and magnetic resonance (MR) imaging arms
- Most ovarian/adnexal lesions initially evaluated with US: O-RADS US is primary assessment tool
- O-RADS MR has ↑ specificity → characterization of lesions indeterminate on US
