Table 1.

Tabulated contrast-to-noise ratio (CNR) for various GNP concentrations based on XFCT and transmission CT images of the “high” and “low” phantom configurations.

GNP Concentration (wt. %)	Contrast-to-Noise Ratio (CNR)
GNP Concentration (wt. %)	XFCT	Transmission CT
	“High” Configuration^a
0.1	6.04	2.94
0.3	12.6	3.14
0.5	14.5	4.77
	“Low” Configuration^b
0.03	3.71	2.43
0.08	5.39	2.87
0.3	12.6	3.15

Concentrations of GNP/PBS inserts for the “high” configuration were 0.1, 0.3, and 0.5 wt. %

Concentrations of GNP/PBS inserts for the “low” configuration were 0.03, 0.08, and 0.3 wt. %
