The values of ADC and DC avg in MSI group and MSS group were highly correlated (r=0.906, 0.868, P<0.001).The AUC of EC MSI predicted by ADC, DC avg, FA, VRA and Exat values were 0.698, 0.720, 0.783, 0.743 and 0.725, respectively. There was no statistical difference among each AUC (P>0.05).
A 63 years old patient with poorly differentiated endometrioid adenocarcinoma. 1a was the original image of DTI sequence, location of lesions was shown by the yellow arrow on; 1B was the DC avg map, DC avg value was 0.718×10-9mm2/s; 1c was the FA map, FA value was 0.260; 1d was the Iso map, Iso value was 229.340; 1e was the VRA map, VRA value was 0.051; 1f was the Exat map, Exat value was 0.652; 1g was the T2-wt map, T2-wt value was 229.340; 1h was the ADC map of DWI sequence, ADC value was 0.740×10-3mm2/s
