New framework READII-2-ROQC identifies confounding factors in imaging AI models

By PulseAugur Editorial · [1 sources] ·

A new open-source framework called READII-2-ROQC has been developed to address confounding factors in radiomics and imaging foundation models. This framework uses volume-preserving negative controls to evaluate whether extracted features truly represent tumor biology or are influenced by factors like tumor volume or acquisition artifacts. When applied to public cancer imaging cohorts, READII-2-ROQC demonstrated that some models maintain performance even after spatial structure is destroyed, indicating volume-driven confounding, while others show sensitivity to perturbations. AI

IMPACT This framework could improve the interpretability and reliability of imaging AI models, leading to more accurate diagnostic biomarkers.

    Negative controls reveal volume-driven confounding in radiomics and imaging foundation model features

    arXiv:2607.28423v1 Announce Type: cross Abstract: Radiomics and imaging foundation models promise non-invasive biomarkers of tumour biology, yet predictive signatures may reflect tumour volume or acquisition artifacts rather than meaningful image structure. We introduce READII-2-…
