The advancement of multi-slice CT technology has enabled exact analysis, diagnosis, and treatment of renal and renal tumors. Using contrast agents during CT imaging allows for more accurate acquisition of information regarding blood vessels, organs, and lesions. In this study, we employed three-phase contrast-enhanced CT images of the abdominal region to analyze small-sized renal tumors, explicitly focusing on challenging-to-distinguish types such as papillary Renal Cell Carcinoma (pRCC), chromophobe Renal Cell Carcinoma (RCC), and oncocytoma. The goal is to quantitatively characterize the features of renal tumors and strive for a high-precision discriminatory classification.
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.
