HCC TACE Seg Multimodality annotated hepatocellular carcinoma data set including pre and post TACE multiphasic contrast enhanced CT with voxel level segmentations of liver, tumor mass, portal vein, and abdominal aorta. Dataset Details Field Value Modality CT (multiphasic contrast enhanced) Body part Liver (hepatocellular carcinoma + intrahepatic vessels + abdominal aorta) Task 3D multi class segmentation (4 foreground classes) Patients 105 (68 M / 37 F) Studies ~210 (pre TACE + post TACE per patient) CT series 572 SEG series 105 (one STAPLE fused consensus mask per patient on the pre TACE study) Images 51,968 DICOM slices Format DICOM (images) + DICOM SEG (segmentations) License CC BY 4.0 Each patient was scanned 1–12 weeks (avg ~3 weeks) before their first TACE procedure (pre TACE) and at follow up (~14 weeks post TACE). Only the pre TACE study is segmented. Three independent radiology residents semi automatically segmented each case in AMIRA; senior body radiologist K.M.E. (20+ yrs experience) reviewed all annotations. The released mask is the STAPLE fused consensus of the three rater segmentations. Segmentation Labels The DICOM SEG file for each patient contains four binary segm…
