O-RADS™ is an acronym for an Ovarian-Adnexal Imaging-Reporting-Data System which will function as a quality assurance tool and clinical support system for the standardized description of ovarian/adnexal pathology and its management. A uniform vocabulary using the most predictive internationally agreed upon lexicon descriptors for describing the imaging characteristics of ovarian/adnexal masses has been applied to a data-based risk stratification classification for consistent interpretations leading to appropriate management in clinical practice. The system’s goal is to optimize ovarian cancer outcomes while minimizing unnecessary surgery in patients at low risk of malignancy.
