IVDM3Seg

在一项研究中，研究了长时间卧床 (太空模拟) 对腰椎间盘的影响的研究中，从两个不同阶段的12名受试者中收集了24个至少7个下脊柱ivd的3D多模态MRI数据集。使用Dixon协议用西门子的1.5-Tesla MRI扫描仪扫描每个阶段的每个受试者。因此，每个3D多模态MRI数据集包含四个对齐的高分辨率3D体积: 同相，反相，脂肪和水图像。总共将有96个高分辨率3D MRI体积数据。对于每个IVD，以二进制掩码的形式提供参考手动分割。所有图像 (每个患者四个体积) 和二进制掩模 (每个患者一个二进制体积) 都以神经影像信息学技术计划 (NIFTI) 文件格式存储。

In a study investigating the effects of prolonged bed rest (simulated space environment) on lumbar intervertebral discs (IVDs), a 3D multi-modal MRI dataset was collected from 12 subjects at two distinct stages, with 24 such datasets acquired in total (12 subjects × 2 stages), each containing at least 7 inferior spinal IVDs. Each subject at each scanning stage was scanned using a Siemens 1.5-Tesla MRI scanner with the Dixon protocol. Accordingly, each 3D multi-modal MRI dataset includes four aligned high-resolution 3D volumes: in-phase, out-of-phase, fat-only, and water-only images. This results in an overall total of 96 high-resolution 3D MRI volume datasets. Reference manual segmentations in the form of binary masks are provided for each individual IVD. All imaging volumes (four volumes per patient) and binary masks (one binary volume per patient) are stored in the Neuroimaging Informatics Technology Initiative (NIfTI) file format.
