<h2>Description</h2>

<p>

This is a large publicly available <strong>multi-center lumbar spine MRI dataset</strong> with expert reference segmentations of vertebrae, intervertebral discs (IVDs), and the spinal canal.

The dataset contains <strong>447 sagittal T1- and T2-weighted MRI series</strong> from <strong>218 studies</strong> of <strong>218 patients</strong> with a history of low back pain.

</p>

<p>

Data was collected from four different hospitals. An additional <strong>hidden test set</strong> is used for evaluation in the accompanying SPIDER challenge at

<a href="https://spider.grand-challenge.org/" target="_blank">spider.grand-challenge.org</a>.

</p>

<p>

We release this dataset to promote collaboration and participation in the field of spine segmentation and to improve the diagnostic value of lumbar spine MRI.
