2025年2月21日 · O-RADS MRI serves to guide risk stratification for adnexal lesions discovered in average-risk women with no acute symptoms. When multiple or bilateral lesions are encountered, each lesion should be characterized separately, and the management is driven by the lesion with the highest score.

Begin with Question 1 until an O-RADS MRI Risk Score is displayed. Press the reset button after each lesion to reset the calculator. Question 1: Presence of peritoneal, mesenteric or omental …

O-RADS™ is a clinical support system for the standardized description and classification of ovarian/adnexal lesions. The system consists of two complementary arms: Ultrasound (US) — the primary imaging modality, which is optimized for high sensitivity. Magnetic Resonance Imaging (MRI) — a secondary tool that allows higher specificity.

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...

2022年1月18日 · The O-RADS MRI risk stratification system provides a means for assigning probability of malignancy based on the composition of the lesion, the signal intensity characteristics, and the enhancement pattern of any solid tissue.

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.

Recently, the American College of Radiology (ACR) Ovar-ian-Adnexal Reporting and Data System (O-RADS) MRI com-mittee published a lexicon and risk stratification system for adnexal lesions (8,37–39).

2022年11月22日 · This article reviews the Ovarian-Adnexal Reporting Data System Magnetic Resonance Imaging (O-RADS MRI) score for the characterization of indeterminate ovarian masses. We aim to provide sufficient information to enable readers to …

2025年2月6日 · Applying the O-RADS MRI score requires adherence to a standardized MRI protocol to ensure accurate characterization of ovarian masses. The following imaging sequences are recommended: T2-weighted images: Acquired in both axial and sagittal/coronal planes with a slice thickness of 4 mm.
