RR-Findings: Chest CT Findings Labels for Japanese Radiology Reports
RR-Findings is a labeled dataset of Japanese chest CT radiology reports derived from the MedNLP-SC Radiology Report TNM Staging (RR-TNM) Dataset, released as part of the NTCIR-17 MedNLP-SC shared task.
A total of 243 Japanese radiology reports (covering 27 lung cancer cases, annotated independently by nine board-certified radiologists) were further enriched with multi-label chest CT findings assigned by radiology residents. All labels follow the schema of the CT-RATE dataset.
Labels
Each report is annotated with 18 clinically relevant chest CT findings:
Medical material
Arterial wall calcification
Cardiomegaly
Pericardial effusion
Coronary artery wall calcification
Hiatal hernia
Lymphadenopathy
Emphysema
Atelectasis
Lung nodule
Lung opacity
Pulmonary fibrotic sequela
Pleural effusion
Mosaic attenuation pattern
Peribronchial thickening
Consolidation
Bronchiectasis
Interlobular septal thickening
The labeling schema is based on CT-RATE: https://huggingface.co/datasets/ibrahimhamamci/CT-RATE
