Additional file 3 of Reproducibility of lung cancer radiomics features extracted from data-driven respiratory gating and free-breathing flow imaging in [18F]-FDG PET/CT

Additional file 3. Differences and concordance among free-breathing and data-driven gating PET/CT for all radiomics features calculated separately based on pulmonary lesions localisation. The relative difference in percentage (DIFF%) and the concordance bias coefficient (Cb) are presented for each of the 141 radiomics features derived separately on each group “superior” and “inferior” depending on their anatomical localisation: lesions in the superior lobes versus the inferior regions. Non-reproducible features are marked with a star.
