We aimed to investigate if diffusion kurtosis imaging (DKI) can be applied to differentiate different types of renal cell carcinoma (RCC). For MD, a significant higher value was shown in CCRCC (3.12±0.26) than the rest RCCs (1.03±0.25 for PRCC, 1.78±0.31 for ChRCC and 1.68±0.30 for CDC, p<0.05). For MK，KA and RK, a significant higher value was shown in PRCC (1.52±0.27, 1.93±0.36, 1.21±0.37) than the rest RCCs (1.16±0.23 1.29±0.26, 0.83±0.31 for ChRCC; 0.88±0.21, 1.19±0.33, 0.62±0.29 for CDC and 0.41±0.09, 0.53±0.13, 0.36±0.10 for CCRCC, p<0.05).
