Purpose: To detect fat status and differentiate histotypes of renal masses by using Dixon technique. Materials and methods: This study included 134 solid renal masses. Signal intensity index (SII) and fat fraction (FF) in different histotypes were compared. Results: Only angiomyolipoma (AML), clear cell renal cell carcinoma (RCC), and papillary RCC were confirmed to contain fat. The FF of 16.8% can effectively differentiate AML from clear cell RCC, so did the SII of 9.2% can differentiate clear cell RCC from non-clear cell RCC and rare benign histotypes. Conclusion: Dixon technique successfully evaluated the fat status and histotypes of renal masses.
