Table 2.

Receiver operating characteristic (ROC) curve analysis comparing the ability of the average diffusion signal computed on different shells (b=0, 1000, 2000, 3000, 5000 s/mm²) and the whole multi-shell scheme to differentiate between chronic active (PRL+) and chronic inactive (PRL-) lesions. The table displays a summary of the full performance (area under the curve (auc), accuracy, sensitivity, specificity) from the ROC curve analysis.
