In this paper, we discuss the R2* value and FF value of IDEAL-IQ sequence to differentiate ccRCC from RAMLwvf. The results show that the AUC values of R2* and FF were 0.893 and 0.905 respectively,which made it possible to identify the ccRCC from RAMLwvf before operation.
Fig. 1 The ROI placed in focus area. The white arrow indicated the lesion area. A&B A 55 years old male patient with clear renal cell carcinoma. A was R2* image,the R2* value was 19.5Hz. B was FF image,the FF value was 3.7. B&C A 60 years old female patient of renal angiomyolipoma without visible fat. C was R2* image,the R2* value was 38.7Hz. D was FF image,the FF value was 25.1.
