The Ovarian-Adnexal Reporting and Data System (O-RADS) is an evidence-based clinical support system for ovarian and adnexal lesion assessment in women of average risk. The system has both US and MRI components with separate but complementary lexicons and assessment categories to assign the risk of malignancy. US is an appropriate initial imaging modality, and O-RADS US can accurately help to characterize most adnexal lesions. MRI is a valuable adjunct imaging tool to US, and O-RADS MRI can help to both confirm a benign diagnosis and accurately stratify lesions that are at risk for malignancy. This article will review the O-RADS US and MRI systems, highlight their similarities and differences, and provide an overview of the interplay between the systems. When used together, the O-RADS US and MRI systems can help to accurately diagnose benign lesions, assess the risk of malignancy in lesions suspicious for malignancy, and triage patients for optimal management.
卵巢-附件报告和数据系统（O-RADS）是一种基于证据的临床支持系统，用于评估平均风险女性的卵巢和附件病变。该系统具有超声和 MRI 两个部分，具有单独但互补的词汇和评估类别，以确定恶性肿瘤的风险。超声是一种合适的初始影像学检查方法，O-RADS 超声可以准确地帮助确定大多数附件病变的特征。MRI 是超声的一种有价值的辅助影像学工具，O-RADS MRI 可以帮助确认良性诊断，并准确分层恶性风险的病变。本文将回顾 O-RADS US 和 MRI 系统，强调它们的相似之处和不同之处，并概述系统之间的相互作用。当联合使用时，O-RADS US 和 MRI 系统可以帮助准确诊断良性病变，评估疑似恶性病变的恶性肿瘤风险，并对患者进行最佳管理的分诊。
