Accurate imaging diagnosis of renal oncocytomas remains a challenge for radiologists. Our study retrospectively collected MR imaging of 37 renal oncocytomas and 131 Stage I renal cell carcinoma, compared the diagnostic efficacy between whole-lesion MRI texture analysis and traditional imaging features. Tumor central scar or segmental enhancement inversion showed low sensitivity with high specificity. While whole-lesion MRI texture analysis showed better performance in diagnosis of renal oncocytomas, especially in differentiating oncocytomas with chrommphobe RCC. Whole-lesion MR T2WI texture analysis can be an applicable method in diagnosis of renal oncocytomas.
