Table 3.

Mean and standard deviation of the lesion relative lesion activity (RLA), the relative RLA error, and the lesion recovery coefficient (RC) for simulated standard quality, and predicted high quality (HQ) PET images in the test set.

	GT-HQ PET RLA lesion = 0.3			GT-HQ PET RLA lesion = 0.6
	Lesion RLA (Target: 0.3)	Relative RLA error (Target: low)	Lesion RC (Target: 1)	Lesion RLA (Target: 0.6)	Relative RLA error (Target: low)	Lesion RC (Target: 1)
Simulated standard-quality PET	0.80 ± 0.08	1.68 ± 0.26	0.71 ± 0.10	0.86 ± 0.08	0.44 ± 0.17	0.39 ± 0.05
Predicted high-quality PET	0.57 ± 0.11	0.89 ± 0.35	1.44 ± 0.33	0.77 ± 0.11	0.28 ± 0.18	0.98 ± 0.17

The comparator is the ground-truth (GT) HQ PET. Left panel, lesion RLA was 0.3; right panel, lesion RLA was 0.6.
