Inertia-based K<sub>ep</sub> showed a moderate positive correlation with the CD4<sup>+</sup> TIL level (<i>r</i> = 0.549, <i>p</i> < 0.001), and the Correlation based on K<sub>ep</sub> showed a moderate negative correlation with the CD4<sup>+</sup> TIL level, which also had the highest correlation coefficient (<i>r</i> = -0.616, <i>p</i> < 0.001). The diagnostic efficacy of the above features was assessed by ROC curves. For CD8<sup>+</sup> TILs, ClusterShade of K<sub>ep</sub> had the highest mean area under the curve (AUC) (0.863). For CD4<sup>+</sup> TILs, the Correlation of K<sub>ep</sub> had the highest mean AUC (0.856). <b>Conclusion:</b> The radiomics features of DCE-MRI are associated with the expression of tumor-infiltrating CD8<sup>+</sup> and CD4<sup>+</sup> T cells in AGC, which have the potential to noninvasively evaluate the expression of CD8<sup>+</sup> and CD4<sup>+</sup> TILs in AGC patients.</p>","PeriodicalId":19981,"journal":{"name":"Pathology & Oncology Research","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10277864/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10067572","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
