Relaxivity of Gadoxetate With Respect to [1-¹³C]Pyruvate and Its Metabolites Dissolved in Phosphate-Buffered Saline

Agent	Relaxivity (mM⁻¹ s⁻¹)
[1-¹³C]pyruvate	0.087 +/−0.023
[1-¹³C]lactate	0.12 +/−0.008
[1-¹³C]alanine	1.11 +/− 0.103^a

Note: Pyruvate and lactate relaxivity were measured at a concentration of 24 mM using a hyperpolarized sample. Alanine relaxivity was measured at a concentration of 1.2 M using a non-hyperpolarized sample and saturation recovery (see text).

The relaxivity of alanine differed significantly (P <0.05) from that of pyruvate and lactate.
