| ## 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 |
