What the programme covers
MRI is not one image type. Sequence combinations, planes, contrast, timing, coils, acceleration and field strength determine whether two examinations are comparable for a model task. Programme manifests therefore describe completeness at study level.
What a useful specification includes
A defensible request defines the clinical task, source evidence and acceptance criteria before patient-level data moves. The exact fields and thresholds depend on the intended model claim.
- Anatomy, pathology and examination window
- Required and optional sequences
- Contrast status, field strength and scanner mix
- Plane, resolution and acquisition constraints
- Reports, diagnoses, outcomes or annotations
- Longitudinal and repeated-examination handling
Quality and validation controls
MRI curation resolves series, identifies derived images, checks sequence completeness and preserves the mapping between source DICOM and any converted volume.
- Sequence classification and completeness
- Orientation, dimensions and voxel spacing
- Motion, truncation and acquisition artefacts
- DICOM-to-NIfTI conversion validation
- Patient-safe examination and split logic
Availability, rights and delivery
MRI cohorts can include approved source DICOM, derived NIfTI, sequence maps, manifests, QC results and clinical evidence as defined by the programme.
Public pages describe a sourcing and engineering capability, not guaranteed ready inventory. Each release remains subject to verified programme inventory, programme-specific authorization, privacy review, technical acceptance and buyer licence terms.
Questions, answered directly.
Does one MRI file equal one case?+
No. One examination can contain thousands of DICOM instances across many sequences. Cases should be counted as verified patients or examinations.
Can MRI data include segmentation masks?+
Yes when separately scoped and produced under a qualified annotation and review standard.
Can different scanner vendors be included?+
Yes. Vendor and model diversity should be measured and aligned with the intended training or validation design.
Is brain MRI the only anatomy?+
No. Brain MRI is a published reference programme; other anatomy can be assessed against inventory and authority.
