DeepLesion Benchmark Subset (Balanced 2K)

This dataset is a curated subset of the DeepLesion dataset, prepared for demonstration and benchmarking purposes. It consists of 2,000 CT lesion samples, balanced across 8 coarse lesion types, and filtered to include lesions with a short diameter > 10mm.

Dataset Details

• Source: DeepLesion
• Institution: National Institutes of Health (NIH) Clinical Center
• Subset size: 2,000 images
• Lesion types: lung, abdomen, mediastinum, liver, pelvis, soft tissue, kidney, bone
• Selection criteria:
  • Short diameter > 10mm
  • Balanced sampling across all types
• Windowing: All slices were windowed using DICOM parameters and converted to 8-bit PNG format

Intended Uses

• Embedding demos
• Lesion similarity and retrieval
• Benchmarking medical image models
• Few-shot learning on lesion types

Limitations

• This is a small subset of the full DeepLesion dataset
• Not suitable for training full detection models
• Labels are coarse and may contain inconsistencies
