Previous researchs had proved that corticomedullary differentiation contrast ratio obtained from SLEEK was significantly positively correlated with eGFR. But they did not quantitatively analyze the diagnostic performance of SLEEK and did not compare it to other imaging methods. We obtained the area under the curve (AUC) by making the ROC curve to compare the diagnostic performance between SLEEK and DWI. DWI, previous reports have shown that ADC values are positively correlated with eGFR, may be an effective methods to evalaute renal function. Therefor we compared SLEEK with DWI to assess the diagnostic value of SLEEK.
