Abstract Background and purpose Renal cell carcinoma (RCC) is a heterogeneous group of cancers. The collagen fiber content in the tumor microenvironment of renal cancer has an important role in tumor progression and prognosis. A radiomics model was developed from dual-energy CT iodine maps to assess collagen fiber content in the tumor microenvironment of ccRCC. https://www.alarecre.com/Wizarding-World-Harry-Potter-Scar-and-Glasses-iPhone-13-Pro-MagSafe-Case-p90262/
