Table 2:
Distribution of CT scans across different anatomical coverage (CH: chest, ABD: abdomen, PEL: pelvis) and contrast phases (non-contrast, arterial, venous, delayed) for the WAW-TACE, VinDr-Multiphase, and C4KC-KiTS datasets. “None” denotes partial scans limited to specific organs, e.g., liver-only or kidney-only coverage.
