2022年1月18日 · Recently, the American College of Radiology (ACR) Ovarian-Adnexal Reporting and Data System (O-RADS) MRI committee published a lexicon and risk stratification system for adnexal lesions (8, 37 – 39).

Learn how to incorporate O-RADS MRI in the evaluation of patients with adnexal lesions in clinical practice through the use of lexicon terms, imaging techniques and risk stratification system. Viewers will become more familiar with O-RADS MRI and develop an approach to assess lesions in a stepwise algorithmic manner.

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.

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.

2019年11月5日 · 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 …

4 天之前 · It was based on a largely consecutive patient cohort with adnexal lesions and available US examinations (2017–2022) , which has since been updated with 15 more months of patient registration (November 2022–January 2024). Inclusions were patients managed surgically (within 180 days from their sonogram) or conservatively.

O-RADS1类通常表示几乎可以肯定是良性的，不用太过紧张；O-RADS2类也是良性可能性大，但需要定期复查。 而到了O-RADS3类，虽然还是倾向于良性，但有一定的不确定性，需要更密切地关注和随访。 如果是O-RADS4类或5类，那就要高度警惕了，恶性的风险相对较高，可能需要进一步的检查🔬，如活检等，来明确诊断🩺，并制定相应的治疗方案。 💕所以，当发现卵巢附件包块时，不要盲目恐慌，要及时与医生👨‍⚕️沟通，了解O-RADS分类情况，以便采取合适的应对措施。 卵巢 …

2022年7月15日 · 在使用造影剂30秒后显示信号强度（SI）高于子宫肌层的病变（高风险的视觉评估），可以安全地将卵巢-附件报告和数据系统（O-RADS）的MRI评分定为5。 然而，对于有实性组织的病变，如果视觉评估为低风险（30秒和60秒的SI均低于子宫肌层）或视觉评估为中度风险（30秒的SI低于子宫肌层，60秒的SI高于子宫肌层，但T2和弥散加权成像SI不低），则应将O-RADS MRI评分定为4。 原文出处：

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 nodularity or irregular thickening, with or without ascites?

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.
