摘      要：Radiomic analysis has exponentially increased the amount of quantitative data that can be extracted from a single *** imaging biomarkers can aid in the generation of prediction models aimed to further personalized ***,the generalizability of the model is dependent on the robustness of these *** purpose of this study is to review the current literature regarding robustness of radiomic features on magnetic resonance ***,a phantom study is performed to systematically evaluate the behavior of radiomic features under various conditions(signal to noise ratio,region of interest delineation,voxel size change and normalization methods)using intraclass correlation *** features extracted in this phantom study include first order,shape,gray level cooccurrence matrix and gray level run length *** features are found to be non-robust to changing *** robustness assessment prior to feature selection,especially in the case of combining multi-institutional data,may be *** investigation is needed in this area of research.
