SALD T1W: 2D Slice-Based Adult Brain MRI Dataset from China

A 2D slice-based version of structural MRI data from the Southwest University Adult Lifespan Dataset (SALD). The dataset includes T1-weighted brain images from community-dwelling adults aged 19 to 80 in Chongqing, China, collected alongside behavioral and cognitive assessments. It is hosted on Hugging Face by the author 'chehablab' and was last updated in May 2026.

Use Cases

• Train image segmentation models for brain structures based on T1-weighted MRI slices.
• Develop age prediction models based on structural brain imaging features across the adult lifespan.
• Study correlations between brain structure and cognitive or behavioral assessment scores mentioned in the description.
• Benchmark dimensionality reduction or feature extraction methods on 2D neuroimaging data.

Strengths

• Data is derived from a large-scale cross-sectional neuroimaging study designed to characterize the adult lifespan.
• Covers a wide age range of participants from 19 to 80 years old.
• Includes paired behavioral and cognitive assessments for each imaging session.

Limitations

• Column-level documentation and sample data are unavailable, making field semantics unclear.
• The total number of images, rows, and file formats are unknown, limiting suitability assessment.
• Data is sourced from a single university region in China, which may introduce geographic bias.
