A Study Based on CT Radiomics for Distinguishing Benign From Malignant Renal Tumors and Assessing Their Aggressiveness.

A Study Based on CT Radiomics for Distinguishing Benign From Malignant Renal Tumors and Assessing Their Aggressiveness.

To evaluate the efficacy of CT-based radiomics in differentiating benign from malignant renal tumors, predicting nuclear grading of renal cell carcinoma, and assessing T-stage of renal tumors, thereby exploring its clinical application value.

Inclusion Criteria:

• Pathologically confirmed renal tumors (including clear cell renal cell carcinoma, papillary renal cell carcinoma, chromophobe renal cell carcinoma, angiomyolipoma, and oncocytoma).
• Contrast-enhanced CT scan was performed preoperatively.

Exclusion Criteria:

• Pure cystic clear cell renal cell carcinoma
• Poor-quality CT images
