Background
The accurate characterization of ovarian and other adnexal masses is essential for optimal patient management.
The O-RADS is based on a common lexicon to categorize malignancy risk throughout the spectrum of benign and more suspicious lesions with consistent interpretations to provide guidelines for management and stratification of adnexal masses.
Recommendation per the O-RADS schema includes those that carry some risk of malignancy whether discovered incidentally or during the evaluation of a clinical symptom and those discovered on other imaging modalities for which ultrasound is requested for additional lesion characterization.
For risk stratification, the O-RADS US system recommends six categories (O-RADS 0–5), incorporating the range of normal to high risk of malignancy.
