Allen Ivy Glioblastoma Atlas: Annotated Brain Tumor Tissue Images

The Allen Ivy Glioblastoma Atlas contains images of human glioblastoma brain tumor tissue sections. Each section is probed for specific gene expression and paired with an adjacent histologically stained section. All images have been annotated for tumor features by a machine learning process trained by expert medical doctors.

Use Cases

• Train computer vision models for tumor feature segmentation based on annotated tissue images.
• Correlate gene expression patterns with histological features based on paired adjacent tissue sections.
• Develop biomarkers for glioblastoma prognosis based on gene expression and histological image data.

Strengths

• Images are paired, with one showing gene expression and an adjacent section showing histological features.
• Annotations for tumor features were generated by an ML process trained by expert medical doctors.

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.
