Index	Critical value	AUC	Sensitivity (%)	Specificity (%)	Missed diagnosis rate (%)	Misdiagnosis rate (%)
Kep (min-1)	0.561	0.599	65.19	55.40	34.81	44.60
Ve	0.725	0.527	58.04	51.06	41.96	48.94
ADC (×10-3 mm2/s)	0.718	0.739	71.57	61.09	28.43	38.91
ADC + Kep + Ve	-	0.858	83.67	77.18	16.33	22.82

ADC: Apparent diffusion coefficient; AUC: Area under the curve.
