Description
LUMOS is the first publicly available multimodal dataset for lumbar osteoporosis screening. It provides a comprehensive resource to advance AI-driven research in bone health assessment, particularly for automated osteoporosis classification and bone mineral density (BMD) prediction. It can also be used for medical image segmentation, medical image synthesis (e.g., X-ray-to-CT), and other potential applications.
Dataset Overview
Patients: 803
Lumbar X-ray images: 1,620 (anteroposterior or lateral views)
Lumbar CT scans: 280
All DICOM images have been anonymized.
In lumos_clinical_data:
DXA measurements: bmd, bmc, T-scores, Z-scores for vertebrae L1–L4...
Demographics: Age, gender, ethnicity, height, weight, BMI
Osteoporosis labels: 0 = Normal(T-score ≥ −1.0);1 = Osteopenia(−2.5 < T-score < −1.0);2 = Osteoporosis (T-score ≤ −2.5)
