This is a large publicly available multi-center lumbar spine magnetic resonance imaging (MRI) dataset with reference segmentations of vertebrae, intervertebral discs (IVDs), and spinal canal. The dataset includes 447 sagittal T1 and T2 MRI series from 218 studies of 218 patients with a history of low back pain. The data was collected from four different hospitals. There is an additional hidden test set, not available here, used in the accompanying SPIDER challenge on spider.grand-challenge.org. We share this data to encourage wider participation and collaboration in the field of spine segmentation, and ultimately improve the diagnostic value of lumbar spine MRI. This file also provides the biological sex for all patients and the age for the patients for which this was available. It also includes a number of scanner and acquisition parameters for each individual MRI study. The dataset also comes with radiological gradings found in a separate file for the following degenerative changes: 1.    Modic changes (type I, II or III) 2.    Upper and lower endplate changes / Schmorl nodes (binary) 3.    Spondylolisthesis (binary) 4.    Disc herniation (binary) 5.    Disc narrowing (binary) 6.    Disc bulging (binary) 7.    Pfirrman grade (grade 1 to 5). All radiological gradings are provided per IVD level. Repository: https://zenodo.org/records/10159290 Paper: https://www.nature.com/articles/s41597-024-03090-w
