Table 1:

Incidence (%) of MR imaging findings in the necks of patients with head and neck cancers by consensus of 2 radiologists

	Vanishing Border Sign* (T1WI)		Flare Sign* (fsT2WI)		Shaggy Margin* (CET1WI)
	Present	Absent	Present	Absent	Present	Absent
ENS (+)	91	6	90	7	97	0
ENS (−)	10	33	8	35	12	31
Total	101	39	98	42	109	31

Note:—T1WI indicates T1-weighted imaging; fT2WI, fat-suppressed T2-weighted imaging; CET1WI, gadolinium-enhanced T1-weighted imaging.

^*The incidence of MR imaging criteria is significantly different between ENS (+) and ENS (−) necks (P < .0001, Fisher exact test).
