Fig. 6.

Receiver operating characteristic (ROC) curve of the threshold EADC (0.192) and ADC value (1.66 × 10⁻³ mm²/s) was used for differentiating RCC from RAML. The sensitivity and specificity are 84.6 % in EADC and 81.1 % in ADC, respectively. No significant difference was found in area under the ROC curve between EADC and ADC values by U-test analysis (p > 0.05)
