Diagnostic ability of MR imaging criteria for ENS

MR Imaging Findings	Diagnostic Ability (%)
	Sensitivity	Specificity	Accuracy	PPV	NPV
Flare sign (fsT2WI)	77	93	88	83	90
Shaggy margin (CET1WI)	65	99	89	86	86
Short-axis diameter
15 mm	93	66	75	61	94
16 mm	80	85	84	76	88
17 mm	78	84	81	74	87

Note:—fsT2WI indicates fat-suppressed T2-weighted imaging; CET1WI, gadolinium-enhanced T1-weighted imaging; PPV, positive predictive value; NPV, negative predictive value.
