NSCLC PleuralEffusion (PleThora) Voxel level thoracic cavity and pleural effusion segmentations on the NSCLC Radiomics CT collection. Published by Kiser et al. (Medical Physics 2020) as PleThora, "Pleural effusion and thoracic cavity segmentations in diseased lungs for benchmarking chest CT processing pipelines." Dataset Details Field Value Modality CT (chest, contrast and non contrast mixed) Body part Chest — thoracic cavity, pleural effusion Tasks Thoracic cavity 3D segmentation; pleural effusion 3D segmentation CT patients 402 (plus 3 extras for mask coverage: 405 total CT folders) Thoracic cavity masks 402 patients (primary reviewer) + 86 (secondary reviewer) Pleural effusion masks 78 patients (first + second reviewer) + 16 (third reviewer) DICOM slices ~48,568 Mask format NIfTI (.nii.gz) CT format DICOM License CC BY NC 3.0 (NSCLC Radiomics CTs); PleThora masks released under CC BY 3.0. The most restrictive of these (CC BY NC 3.0) governs the combined upload. Subsets and Recommended Ground Truth PleThora ships multiple reviewer tiers for both subsets. The paper's benchmark splits and recommended references are: Thoracic Cavity Whole cavity volume — includes lung, tumor, atelec…
