Adrenal-ACC-Ki67-Seg

Voxel-level segmentation of pathologically-proven Adrenocortical Carcinoma (ACC) tumors on contrast-enhanced CT, with matched Ki-67 proliferation-marker labels.

Dataset Details

Field	Value
Modality	CT (contrast-enhanced)
Body part	Abdomen — adrenal gland (tumor)
Task	3D binary tumor segmentation
Patients	53
Studies	65
CT series	124
SEG series	53 (one per patient)
Images	18,255 DICOM slices
Format	DICOM (images) + DICOM SEG (segmentations) + XLSX (clinical)

No predefined train/val/test split — single cohort of 53 patients with pathologically confirmed ACC imaged between 2006 and 2018. Tumor volumes range from 2.6 to 7,864 cm³ (median ~177 cm³).

Segmentation DICOMs are DICOM SEG objects and reference their source CT series via DICOM metadata. Clinical metadata (demographics, Ki-67 index, follow-up, tumor measurements) is provided in the XLSX spreadsheet.
