Metadata management approaches of the AI4HI projects
| Project | Metadata collection | Metadata types | Models used | Unique characteristics |
|---|---|---|---|---|
| PRIMAGE | Structured e-forms | Imaging, clinical, image radiomic analysis |
DICOM for imaging metadata MIABIS for biological samples and tissue OMOP-CDM for clinical |
Integration of the DICOM and MIABIS standards, and metadata model that captures the biomechanical/signalling behaviour of tumours |
| EuCanImage | Structured e-forms | Imaging, clinical |
DICOM-MIABIS for imaging data Extension of ICGC-ARGO for clinical variables |
Link between imaging and non-imaging data |
| INCISIVE | Structured e-forms | Clinical, biological, imaging |
Multiple terminologies for clinical data (e.g., SNOMED-CT, ICD10, ATC classification) FHIR for communication |
Data Integration Quality Check Tool employed to identify whether data follow the harmonisation requirements defined |
| CHAIMELEON | Structured e-forms | Imaging, clinical |
DICOM for imaging metadata MIABIS for biological samples and tissue OMOP-CDM for clinical |
A multimodal analytical data engine will facilitate interpretation, extraction, data harmonisation, and exploitation of the stored information. The CHAIMELEON repository will ensure the usability and performance of the repository as a tool fostering AI experimentation |
| ProCancer-I | Data upload tool (e-forms) | Imaging, clinical |
DICOM-Radiation therapy for imaging data OMOP-CDM for clinical data |
Provides an extension to OMOP-CDM going beyond radiology/oncology extensions and introduces another model (AI passport) for modeling analysis workflows and AI development |
