Statistical Analysis. Introduction The Standardized Environment for Radiomics Analysis (SERA) Package is a Matlab®-based framework developed at Johns Hopkins University that calculates radiomic features based on guidelines from the Image Biomarker Standardization Initiative (IBSI). Radiomics is an emerging translational field of research aiming to extract mineable high-dimensional data from clinical images. In addition, it also calculates 10 moment invariant features, that are not included in IBSI. Radiomic features not only correlate with genomic data but also may provide complementary information about tumor heterogeneity across the entire tumor volume to improve survival prediction, therefore potentially proving useful for patient stratification. In figure 2, the ICC for all radiomics features in all ROIs were depicted as a heatmap based on four ICC categories. Indeed, statistical analysis was the weakest part of most texture and radiomics studies before 2015 because it tested too many hypotheses (i.e., number of features) for small patient cohorts without correction for type I errors (i.e., false discovery) and without the use of a validation dataset, thereby reporting mere (overfitted) correlations and not actual predictive power. Intraclass correlation coefficients (ICCs) based on a multiple-rating, consistency, 2-way random-effects model were calculated to assess the stability and reproducibility of radiomic features. This influences the quality and usability of the images, which in turn determines how easily and accurately an abnormal characteristic could be detected and characterized. GitHub is where people build software. 1. Then, statistical analysis was performed to assess association of CT radiomics features with metagenes. We also present guidelines for standardization and implementation of radiomics in order to facilitate its transition to clinical use.
