Age-Specific Cerebral Vessel Templates for Healthy Adults Across Four Age Groups

621.8 MB of NIfTI-format brain imaging templates with 0.5mm³ isotropic resolution, created by Chang Xu and last updated in April 2026. The dataset provides intensity, vessel probability, density, and radius maps for four age groups: youth, young adults, middle-aged adults, and older adults. All volumes are stored as floating-point images to preserve quantitative precision.

Use Cases

• Developing age-specific brain atlases based on the provided MRA intensity and Vessel probability templates.
• Analyzing quantitative changes in cerebral vessel density across the lifespan using the Density feature maps.
• Studying vessel radius variations in healthy aging using the Radius feature maps provided in millimeters.
• Spatial normalization of new neuroimaging data using the referenced age-specific T1w structural templates.

Strengths

• Provides data at a high spatial resolution of 0.5mm³.
• Covers four distinct age groups (YO, YA, MA, OA) for lifespan analysis.
• Includes four feature categories (MRA, Vessel, Density, Radius) for anatomical and quantitative analysis.
• Uses floating-point image format to preserve quantitative precision.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
