In Vivo Structural MRI Atlas of Human Thalamic Nuclei in MNI and Custom Template Space

Data for a paper submitted to Scientific Data, including maximum probability thalamic nuclei atlases in both MNI space and a custom template space derived from 20 subjects. The dataset was created by Manojkumar Saranathan of the University of Arizona and includes a segmentation script and test cases. Copyright is held for 2020, intended for research use only.

Use Cases

• Segmenting T1-weighted MRI data into thalamic nuclei based on the provided atlasseg script.
• Comparing thalamic anatomy across populations using the custom template derived from 11 MS and 9 healthy subjects.
• Visualizing thalamic nuclei probability maps in standard MNI space for neuroimaging studies.
• Validating automated thalamic segmentation algorithms using the included set of 5 test cases.

Strengths

• Includes atlases in two standardized spaces: MNI (152 asymmetric 09b) and a custom template from 20 subjects.
• Provides a segmentation script (atlasseg) and a set of 5 test cases for validation.
• Contains detailed auxiliary files like a color table for visualization and spatial probability maps for 11 left and 11 right nuclei.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
