2024年12月20日 · For risk stratification, the O-RADS US system uses five categories (O-RADS 1–5), from normal (1) to high risk of malignancy (5). An O-RADS US 0 (zero) category is used for an incomplete evaluation.

The Ovarian-Adnexal Reporting and Data System (O-RADS) US risk stratification and management system is designed to provide consistent interpretations, to decrease or eliminate ambiguity in US reports resulting in a higher probability of accuracy in assigning risk of malignancy to ovarian and other adnexal masses, and to provide a management reco...

2023年9月12日 · These data confirmed that an O-RADS US 2 score conferred a near 100% chance of benignity, while the diagnostic performance of an O-RADS US 4 score was the optimal cutoff for malignancy characterization.

2020年12月23日 · O-RADS is a recent addition to the American College of Radiology (ACR) reporting and data systems and consists of ultrasound (US) and MRI arms. Since most ovarian or adnexal lesions are first detected with US, O-RADS US …

2024年3月7日 · O-RADS is an acronym for Ovarian-Adnexal Reporting & Data System. It’s a system healthcare providers use to classify ovarian and adnexal lesions on ultrasound and MRI images. O-RADS helps providers across the U.S. interpret test results more reliably and consistently. It also reduces the risk of false ovarian cancer diagnoses. What is O-RADS?

2023年9月12日 · The Ovarian-Adnexal Reporting and Data System (O-RADS) US v2022 update provides additional user clarity, improves specificity, better aligns with existing consensus statements, and offers more directed management recommendations.

2024年2月20日 · The Ovarian-Adnexal Imaging Reporting and Data System, (O-RADS), aims to ensure that there are uniform unambiguous sonographic and MRI evaluations of ovarian or other adnexal lesions, accurately assigning each lesion to a risk category of malignancy being present, and which informs the appropriate management that could be instituted.

First published in 2019, the Ovarian-Adnexal Reporting and Data System (O-RADS) US provides a standardized lexicon for ovarian and adnexal lesions, enables stratification of these lesions with use of a numeric score based on morphologic features to indicate the risk of malignancy, and offers management guidance.

2022年7月13日 · There are 6 O-RADS US risk stratification categories, 0 for the technically inadequate exam and 1–5, which range from normal to high risk of malignancy (Table 1). 2 These categories harmonize the pattern-based approach commonly used in North America with the statistics used in the IOTA models and are based on malignancy prevalence identified fro...

In this cohort study of 913 patients with 1014 adnexal lesions, an O-RADS US 4 was the optimum cutoff for diagnosing cancer, with a sensitivity of 90.6%, specificity of 81.9%, positive predictive value of 31.4%, and negative predictive value of 99.0%, which was statistically significant.
