## Dataset description
This workshop and challenge extended multi-atlas labeling methods beyond the brain to clinically acquired abdominal CT. Fifty portal venous phase scans were selected under IRB supervision from colorectal cancer and ventral hernia study cohorts, providing a standardized dataset to benchmark abdominal anatomy segmentation.

**Number of CT volumes**: 50

**Contrast**: Contrast-enhanced (portal venous phase)

**CT body coverage**: Abdomen

**Does the dataset include any ground truth annotations?**: Yes

**Original GT annotation targets**: Spleen, right kidney, left kidney, gallbladder, esophagus, liver, stomach, aorta, inferior vena cava, portal vein and splenic vein, pancreas, right adrenal gland, left adrenal gland

**Number of annotated CT volumes**: 30

**Annotator**: Human

**Acquisition centers**: Vanderbilt University Medical Center (VUMC)

**Pathology/Disease**: Colorectal cancer and ventral hernia cases
