Table 1

Quantitative measurements of benign and metastatic LNs.

	Benign; 𝑛=17	Metastatic; 𝑛=48	𝑡	𝑃
ADC (×10^−3 mm^2/s)	1.443±0.406	0.849±0.111	2.629	0.011
BF (mL/100 g/min)	67.82±13.84	114.62±14.26	3.336	0.002
BV (mL/100 g)	19.36±7.34	32.15±13.21	1.006	0.209
MTT (s)	9.46±3.23	5.56±0.39	2.346	0.002

ADC = apparent diffusion coefficient, BF = blood flow, BV = blood volume, and MTT = mean transit time.
