As most ovarian or adnexal lesions are first detected with US, O-RADS US is considered the primary assessment tool. After many years of collaboration, the international multidisciplinary O-RADS committee published the O-RADS US lexicon in 2018, which was then applied to a risk stratification and management system in 2020.

The goal with this system design is to provide more consistent interpretations, minimize or eliminate ambiguity in US reporting, and provide a risk of malignancy and management recommendation for each type of lesion or risk category. Ultimately, use of the system will result in more accurate diagnoses and optimal patient…
