The buyer must be able to inspect the evidence
Every material claim about case count, sequence, label, demographic field and commercial right should have a source. The dataset card records definitions, exclusions, missingness and known limitations. Supplier agreements and privacy records remain available for diligence under appropriate confidentiality controls.
Quality is task-specific
A technically readable image may still be unsuitable for a target model. Acceptance criteria therefore cover the intended task: sequence completeness for MRI, reconstruction and field of view for CT, annotation standards for segmentation, and cohort separation for validation.
Derived data remains traceable
NIfTI volumes, previews, masks and machine-readable metadata are linked back to pseudonymous study and series identifiers. The process should be reproducible without preserving direct patient identifiers.
Questions, answered directly.
Is de-identification enough for commercial use?+
No. The supplier must also have authority to process and license the data for the agreed commercial purpose.
Does every dataset need segmentation masks?+
No. The required ground truth depends on the model task. Segmentation masks add value only when clinically appropriate and reliably produced.
What is provenance?+
Provenance is the documented history of where data came from, how it was transformed and how each label or derived file was produced.
