Fracture Detection on Cervical Spine CT

This dataset is composed of merged CT scans of the cervical spine in multi- frame Digital Imaging and Communications in Medicine (DICOM) format, collected from emergency patients at St. Michael's Hospital between May 1, 2004 and July 1, 2021. Images are provided in the axial axis and bone window kernel. The dataset includes a total of 1016 CT scans: 508 with fracture(s) matched with an equal number of CT scans without cervical spine fracture. Imaging studies positive for cervical spine fracture were annotated with a segmented mask over the fracture region. The segmentation provide users with pixel level information regarding fracture features and is provided as an associated DICOM file for each positive scan.本数据集由2004年5月1日至2021年7月1日期间，从圣迈克尔医院（St. Michael's Hospital）急诊患者处收集的多帧医学数字成像和通信（Digital Imaging and Communications in Medicine，DICOM）格式颈椎CT扫描影像整合而成。影像以轴位视图与骨窗重建内核格式提供。本数据集总计包含1016例CT扫描：其中508例存在颈椎骨折，另有等量的508例无颈椎骨折的扫描作为对照。针对颈椎骨折阳性的影像，已通过覆盖骨折区域的分割掩码完成标注。该分割掩码可为使用者提供骨折特征的像素级信息，并以关联的DICOM文件形式随每一份阳性扫描一并提供。
