IDEAL-IQ is a new scanning sequence based on the principle of three-point Dixon asymmetric echo technology. The images of water phase, lipid phase, in-phase, reverse phase, fat fraction and R2* relaxation images can be generated at the same time in one scan to realize the quantitative measurement of fat fraction. The R2* value of the ccRCC group was greater than that of the RAMLwvf group, and the FF value was lower than RAMLwvf group, the difference was statistically significant (P <0.05). The AUC value of R2* value and FF value for identifying ccRCC with RAMLwvf groups are 0.893 and 0.905.
