Access O-RADS US

Ultrasound is the primary imaging modality of the female pelvis which allows adequate evaluation of most adnexal lesions using transvaginal and transabdominal technique. The O-RADS US lexicon uses terms supported in the literature and by the International Ovarian Tumor Analysis (IOTA) group to describe ovarian/adnexal lesions and assign a risk of malignancy. Imaging and clinical management recommendations accompany the risk assessment categories to optimize patient outcomes.
