本研究旨在评估基于卵巢-附件报告和数据系统（O-RADS）磁共振成像（MRI）在 sonographically 未确定附件性肿块的女性中实施结构化报告是否能够改善放射科医师、转诊者和患者/护理员之间的沟通，并提高诊断附件恶性肿瘤的表现。我们回顾性地分析了2019-2022年期间用于区分附件性肿块的MRI报告，包括实施O-RADS MRI前后的报告；我们对56名患者/护理员和9名妇科肿瘤学专家（“转诊者”）进行了关于报告可解读性/清晰度/满意度的调查；利用Fisher确切检验和卡方检验进行前后实施报告的比较。我们通过接受者操作特征曲线进行诊断表现评估。总共包括了123份实施O-RADS MRI之前的报告和119份实施之后的报告。患者/护理员的调查回应率为35.7%（20/56），转诊者的回应率为66.7%（6/9）。对于患者/护理员，与非结构化报告相比，O-RADS MRI报告更清晰（p < 0.001）且更令人满意（p < 0.001），但解读能力并没有显著不同（p = 0.14），因为术后实施报告中有28.0%（28/100）被认为难以解读，术前实施的报告有38.0%（38/100）被认为难以解读。对于转诊者来说，O-RADS MRI报告更清晰、更令人满意且更易解读（p < 0.001）；只有1.3%（1/77）被认为难以解读。对于区分良性和恶性附件病变，O-RADS MRI的曲线下面积为0.92（95%可信区间[CI]，0.85-0.99），敏感度为0.81（95% CI，0.58-0.95），特异度为0.91（95% CI，0.83-0.96）。由于术前报告中使用了许多不同的短语来描述恶性肿瘤的可能性，无法计算实施之前的诊断表现。利用O-RADS MRI实施标准化结构化报告对于区分附件性肿块的良性和恶性提高了患者/护理员和转诊者的清晰度和满意度。转诊者的解读能力有所改善，但患者/护理员的解读能力仍然有限。版权所有 © 2023 The Association for University Radiologists.

This study aimed to evaluate whether implementing structured reporting based on Ovarian-Adnexal Reporting and Data System (O-RADS) magnetic resonance imaging (MRI) in women with sonographically indeterminate adnexal masses improves communication between radiologists, referrers, and patients/caregivers and enhances diagnostic performance for determining adnexal malignancy.We retrospectively analyzed prospectively issued MRI reports in 2019-2022 performed for characterizing adnexal masses before and after implementing O-RADS MRI; 56 patients/caregivers and nine gynecologic oncologists ("referrers") were surveyed about report interpretability/clarity/satisfaction; responses for pre- and post-implementation reports were compared using Fisher's exact and Chi-squared tests. Diagnostic performance was assessed using receiver operating characteristic curves.A total of 123 reports from before and 119 reports from after O-RADS MRI implementation were included. Survey response rates were 35.7% (20/56) for patients/caregivers and 66.7% (6/9) for referrers. For patients/caregivers, O-RADS MRI reports were clearer (p < 0.001) and more satisfactory (p < 0.001) than unstructured reports, but interpretability did not differ significantly (p = 0.14), as 28.0% (28/100) of postimplementation and 38.0% (38/100) of preimplementation reports were considered difficult to interpret. For referrers, O-RADS MRI reports were clearer, more satisfactory, and easier to interpret (p < 0.001); only 1.3% (1/77) were considered difficult to interpret. For differentiating benign from malignant adnexal lesions, O-RADS MRI showed area under the curve of 0.92 (95% confidence interval [CI], 0.85-0.99), sensitivity of 0.81 (95% CI, 0.58-0.95), and specificity of 0.91 (95% CI, 0.83-0.96). Diagnostic performance of reports before implementation could not be calculated due to many different phrases used to describe the likelihood of malignancy.Implementing standardized structured reporting using O-RADS MRI for characterizing adnexal masses improved clarity and satisfaction for patients/caregivers and referrers. Interpretability improved for referrers but remained limited for patients/caregivers.Copyright © 2023 The Association of University Radiologists. Published by Elsevier Inc. All rights reserved.
