Short axis length and nIC values of LN in different N stages.

			Short axis length (cm)	nIC-A	nIC-P	nIC-D
			N0	25	51	0.48 ± 0.07	0.18 ± 0.10	0.56 ± 0.39	0.64 ± 0.30
N1	15	24	0.58 ± 0.26	0.20 ± 0.05	0.44 ± 0.08	0.50 ± 0.10
N2	16	64	0.66 ± 0.27	0.12 ± 0.09	0.31 ± 0.16	0.37 ± 0.17
N3	15	251	1.1 ± 0.64	0.16 ± 0.09	0.35 ± 0.13	0.49 ± 0.23
N0	25	51	0.51 ± 0.10	0.18 ± 0.10	0.56 ± 0.39	0.64 ± 0.30
NX	46	339	0.98 ± 0.60	0.15 ± 0.09	0.35 ± 0.14	0.47 ± 0.22

represents the number of patients. represents the number of LNs measured. No statistically significant differences in short axis length were observed between N0 and N1 (), while statistically significant differences were found between the remaining N stages (). Of all the contrast-enhanced phases, nIC values between N0 and other N stages showed statistically significant differences in the portal phase only.
