Table 4.

Comparison of lesion SUL values between the radiotracers 1 h p.i. for all six patients (Comparison between variable was done by paired sample t-test), For comparison of SULpeak of metastases and lesions, see Table S3

Radiotracer	SULpeak (mean ± SD, range)	P-value	SULavg (mean ± SD, range)	P-value
[68Ga]Ga-DOTAGA.(SA.FAPi)2	12±3.9 (9.5-12.5)	0.3488	7.6±2.7 (3.6-9.8)	0.3828
[68Ga]Ga-DOTA.SA.FAPi	9.5±3 (5.4-14.6)		5.7±3 (2.5-8.9)
[18F]FDG	7.8±5.4 (4.2-10.9)	0.1535*	4.2±2.9 (2.2-8)	0.0619*

^* P-values derived by comparing the SUL peak and average values between [⁶⁸Ga]Ga-DOTAGA.(SA.FAPi)₂ and [¹⁸F]FDG.
