This dataset contains population-averaged T2w MRI atlases of paraspinal muscles at theL4-L5 and L5-S1 levels. Two releases are included in the repository. The 2018 release contains atlases made with left-and-right symmetry while the 2019 release includes asymmetric atlases with anatomical labels.
The atlases were made with 117 patients aged between 30 and 59 years old with commonly diagnosed lumbar pathologies. For atlas construction, the population was divided into three groups: 30-39, 40-49, and 50-59 years old, and for each group,19-21 subjects were included for each of male and female cohorts.
All images are provided in NIfTI-1 format. This dataset is released with the CC BY-NC-SA 3.0 license and is based on the following publication:
