Figure 5.

Graph shows receiver operating characteristic (ROC) curve for exponential apparent diffusion coefficient (exponential ADC). Area under the curve, which represents the probability the lesion, will be classified accurately as benign or malignant according to the exponential ADC value, is 0.868. ROC curve analysis is suggesting that exponential ADC >0.4 indicates the possibility of malignancy in the breast lesion with 93.9% (95% CI 85.0 – 98.3) sensitivity and 82.6% specificity (95% CI 61.2 ¬– 95)
