Table 1 Overall patient- and region-based diagnostic accuracy of diffusion-weighted imaging and positron emission tomography and computed tomography n (%)

	Sensitivity	Specificity	PPV	NPV	Accuracy
Patient-based DWI (n = 25)	8/9 (88.9)	7/16 (43.8)	8/17 (47.1)	7/8 (87.5)	15/25 (60.0)
PET/CT (n = 25)	4/9 (44.4)	15/16 (93.8)	4/5 (80.0)	15/20 (75.0)	16/25 (64.0)
Region-based DWI (n = 200)	30/36 (83.3)	84/164 (51.2)	30/110 (27.3)	84/90 (93.3)	114/200 (57.0)
PET/CT (n = 200)	14/36 (38.9)	158/164 (96.3)	14/20 (70.0)	158/180 (87.8)	172/200 (86.0)
