Table 7 Image Biomarker Standardisation Initiative standardization framework: Key phases and achievements

Phase	Timeline	Key achievements	Impact on reproducibility
IBSI phase 1	2016-2020	Standardized definitions for > 170 features; digital phantoms; benchmark values across multiple software platforms	Established common mathematical language; enabled cross-platform comparison
IBSI phase 2	Completed February 2024	Formalized preprocessing workflow (discretization, interpolation, filtering); expanded test phantoms for CT, MRI, PET pipelines	Entropy coefficient of variation decreased from 34% to 7%
Reporting guidelines	Ongoing	Transparent documentation of discretization, filtering, ROI handling, feature selection rationale	Improved study reproducibility and meta-analytic comparability
Compliance tools	Available	Online validation portal; excel-based reference sheets; benchmark feature values	Software platforms (PyRadiomics, LIFEx, SERA, RaCaT) can verify compliance

IBSI: Image Biomarker Standardisation Initiative; CT: Computed tomography; MRI: Magnetic resonance imaging; PET: Positron emission tomography; ROI: Region of interest.
