Contrast-enhanced multi-slice 3D CT images enable highly accurate analysis, diagnosis, and treatment of the kidney. Contrast-enhanced CT images provide more accurate information about blood vessels, organs, and lesions. Abdominal multiphase contrast-enhanced CT images are used and analyzed renal tumors of pallidocystic renal cell carcinoma (ccRCC), pigmented renal cell carcinoma (chRCC), papillary renal cell carcinoma (pRCC), angiomyolipoma, and oncocytoma. By analyzing these multiphase changes, the features of kidney tumors are extracted and classify them with high accuracy.
