超50万张膝关节X光片，含详细临床数据，助力骨关节炎研究。
Emory Knee Radiograph (MRKR) Dataset
- 收集8.3万患者50多万张膝关节X光，40%为非裔
- 包含疼痛评分、诊断编码等罕见临床信息
- 适合研究种族差异的骨关节炎，也适用于医疗AI开发
Emory膝关节X光（MRKR）数据集是包含83,011名患者共计503,261张膝关节X光片的大规模、人口多样性数据集，其中40%为非裔美国人。该数据集以DICOM格式提供影像数据，并附有详细临床信息，包括患者自报疼痛评分、诊断代码和操作代码，这些在同类数据集中并不常见。此外，数据集还包含图像侧别、拍摄体位及金属植入物存在等影像元数据，显著提升其科研与模型开发价值。MRKR填补了现有数据集在代表性方面的关键空白，尤其有助于针对少数族裔群体研究骨关节炎及相关结局，为临床医生和研究人员提供了宝贵资源。
原文摘要 · Abstract (English)
The Emory Knee Radiograph (MRKR) dataset is a large, demographically diverse collection of 503,261 knee radiographs from 83,011 patients, 40% of which are African American. This dataset provides imaging data in DICOM format along with detailed clinical information, including patient-reported pain scores, diagnostic codes, and procedural codes, which are not commonly available in similar datasets. The MRKR dataset also features imaging metadata such as image laterality, view type, and presence of hardware, enhancing its value for research and model development. MRKR addresses significant gaps in existing datasets by offering a more representative sample for studying osteoarthritis and related outcomes, particularly among minority populations, thereby providing a valuable resource for clinicians and researchers.
