SPIDER Lumbar Spine MRI Dataset
SPIDER is a multicenter lumbar-spine MRI dataset containing sagittal T1-weighted and T2-weighted series with reference segmentations of the vertebrae, intervertebral discs and spinal canal.
The SPIDER dataset is distributed under the Creative Commons Attribution 4.0 International license (CC BY 4.0), which permits commercial reuse with appropriate attribution.
The current official SPIDER data page reports 544 sagittal T1- and T2-weighted MRI series from 257 patients. The earlier publication described a public release of 447 series from 218 patients; the values in this record reflect the expanded dataset currently listed on the official project page. Images and segmentation masks are distributed as MetaImage files.
