Voxel-level recovery of the oxygen-transfer constant from exported DSC-MRI capillary-function maps (results and analysis code)

Derivative numerical data and analysis code accompanying *Model-based oxygen extraction capacity from capillary-function DSC-MRI: voxelwise verification and parameter sensitivity* (Öchsner, Liebig, Forbrig, Reis). The study examined native-grid DSC-MRI transit-time and model-based oxygen-extraction maps from 122 adults with untreated IDH-wildtype glioblastoma, processed using Cercare Medical Neurosuite v16.2 (release-2023-02-01-03). It recovered the implemented model constant, verified the exported values within storage precision under a specified rounding assumption, and assessed how changing the constant affects absolute values, normal-appearing white-matter-normalised measurements, rankings and tumour-compartment contrasts. The alternative constant is illustrative, not a physiological recalibration. The deposit contains non-spatial derivative tables and numerical summaries, source-linked reported results, analysis code, unit tests and independent cross-checks. A public script reproduces 22 selected numerical checks from these data. The source-image extraction script `extract_voxels_export_grid.py` is provided as a separate file for the same record (SHA-256 `b71a80399200527463850e346c4a0a8689769992fc94a368d4dc5b7a0221009b`); verify it appears on the Zenodo draft before publishing. The script produces restricted spatial voxel tables; those tables are not public. Spatial voxel-level data capable of reconstructing patient images are not publicly available under the institutional ethics approval. Public participant keys are linked to the companion feature dataset (doi:10.5281/zenodo.21908596). This deposit does not establish physiological validity of OEFmax.
