Table 4

Performance of volumetric approaches ((C), (DCE), and (DWI)).

	Sensitivity [%]	Specificity [%]	Accuracy [%]	Cut-off [%]	AUC
(C) change	0.86	0.73	0.79	37.4	0.76
(DCE) change	0.86	0.93	0.93	34.2	0.90
(DWI) change	0.64	0.94	0.76	39.1	0.81

Note: (C), conventional T2-weighted volumetry; (DWI), diffusion-weighted imaging volumetry; (DCE), dynamic contrast enhanced volumetry; AUC, area under ROC.
