## Dataset description
CT-ORG contains 140 CT scans from diverse sources, each with 3D segmentations of five organs, and brain labels in some cases. The dataset covers a wide range of imaging conditions and includes both benign and malignant liver lesions, as well as metastatic disease in bones and lungs, providing a challenging benchmark for multi-class organ segmentation.
**Number of CT volumes**: 140
**Contrast**: Both contrast-enhanced and non-contrast; includes PET-CT derived scans
**CT body coverage**: Abdominal and full-body
**Does the dataset include any ground truth annotations?**: Yes
**Original GT annotation targets**: Liver, urinary bladder, lungs, kidneys, bone
**Number of annotated CT volumes**: 140
**Annotator**: Human (lungs and bones partly from morphological algorithms)
**Acquisition centers**: Multiple global institutions, Ludwig Maxmilian University of Munich, Radboud University Medical Center of Nijmegen, Poly-technique & CHUM Research Center Montreal, Tel Aviv University, Sheba Medical Center, IRCAD Institute Strasbourg and Hebrew University of Jerusalem. The PET-CT images all derive from Stanford Healthcare.
**Pathology/Disease**: Benign and malignant liver lesions, metastatic disease in bones and lungs

**Original dataset format**: nifti
