ROC curves for combined PET/DWIMRI for the detection of local HNSCC recurrence after radio(chemo)therapy. Patient-per-patient evaluation: AUC (95% CI) PET/DWIMRI = 0.954 (0.903–1.000). Lesion-per-lesion evaluation: AUC (95% CI) PET/DWIMRI = 0.939 (0.887–0.990). The ROC curve for lesions was calculated taking data clustering into consideration
