Table 1. Summary of fs and non-fs BOLD measurements in H460 and A549 tumors.

From A to D: ΔSI(%), R₂*(air), R2*(O₂) and ΔR₂*. Values in the cells are mean±std (range: minimum to maximum). p-values were calculated from unpaired two-sample Student’s t-test for H460 vs. A549 and paired t-test for fs vs. non-fs.

A. ΔSI(%)
	fs	non-fs	p-value (fs vs non-fs)
H460	2.1±9.4 (−27.1 to 16.9)	3.4±8.9 (−20.0 to 19.5)	0.048*
A549	8.7±12.9 (−9.5 to 43.1)	10.0±10.9 (−9.1 to 32.2)	0.45
p-value (H460 vs A549)	0.076	0.046*

B. R2*air(s−1)
	fs	non-fs	p-value (fs vs non-fs)
H460	86.2±19.8 (55.9 to 128.5)	87.3±20.0 (56.4 to 129.3)	0.0009*
A549	116.4±21.9 (85.0 to 171.6)	119.4±22.2 (83.8 to 166.7)	0.017*
p-value (H460 vs A549)	8×10−5*	4×10−5*

C. R2*O2(s−1)
	fs	non-fs	p-value (fs vs non-fs)
H460	86.3±21.7 (54.5 to 133.1)	86.7±21.8 (51.2 to 133.2)	0.4
A549	109.4±20.1 (79.1 to 146.3)	115.1±22.5 (80.7 to 145.9)	1×10−4*
p-value (H460 vs A549)	0.002*	0.0003*

D. ΔR2*(s−1)
	fs	non-fs	p-value (fs vs non-fs)
H460	0.1±5.5 (−10.1 to 11.9)	−0.7±5.7 (−9.8 to 12.4)	0.12
A549	−7.1±8.1 (−25.3 to 4.3)	−4.3±7.9 (−21.2 to 9.2)	0.007*
p-value (H460 vs A549)	0.03*	0.11

^*indicates p<0.05.
