To evaluate the findings of magnetic resonance mammography for suspicious nipple discharge based on breast imaging-reporting and data system magnetic resonance imaging (MRI) descriptors and establish any correlations with the histopathologic diagnoses.
Forty-seven patients with suspicious nipple discharge underwent MRI using a 1.5-T system. Images were evaluated for a signal of abnormal discharge, related abnormal enhancement according to the breast imaging-reporting and data system MRI descriptors, and the presence of clustered ring enhancement and were compared with the histopathologic diagnoses established in 39 lesions.
The most common finding in patients with suspicious nipple discharge was non-masslike enhancement. Seventeen malignant and 22 benign lesions were detected. The most frequent findings in the malignant lesions were "segmental" (59%), "heterogeneous" (57%), and plateau pattern (40%). Clustered ring enhancement was found in 60% of the enhanced malignant lesions (P = 0.002). The combination of segmental distribution and clustered ring enhancement showed a significant association with malignant lesions (P = 0.004).
Magnetic resonance imaging provides clinically useful information in patients with suspicious nipple discharge.
基于乳腺影像报告和数据系统磁共振成像（MRI）描述符评估磁共振乳腺成像对可疑乳头溢液的检查结果，并建立与组织病理学诊断的相关性。
47例可疑乳头溢液患者使用1.5-T系统进行MRI检查。根据乳腺影像报告和数据系统MRI描述符评估图像中异常溢液信号、相关异常强化情况以及簇状环形强化的存在，并与39个病变的组织病理学诊断结果进行比较。
可疑乳头溢液患者最常见的表现为非肿块样强化。共检测出17个恶性病变和22个良性病变。恶性病变中最常见的表现为“节段性”（59%）、“不均匀性”（57%）和平台型（40%）。60%的强化恶性病变中发现簇状环形强化（P = 0.002）。节段性分布与簇状环形强化相结合与恶性病变显著相关（P = 0.004）。
磁共振成像为可疑乳头溢液患者提供了临床有用信息。
