	MV (ml)	1.22 [0.61–2.90]	1.45 [0.80–3.30]	0.97 [0.97–0.98]
Liver	SULmean (g/ml)	1.66 [1.52–1.84]	1.77 [1.60–1.96]	0.87 [0.84–0.90]
	CV (%)	12.83 [11.71–14.49]	10.96 [9.55–12.41]	0.58 [0.48–0.66]
Lesion/liver	LLRmax	2.68 [1.81–4.58]	2.32 [1.51–4.04]	0.97 [0.97–0.98]
	LLRpeak	1.67 [1.12–2.86]	1.51 [1.01–2.69]	0.99 [0.99–0.99]

All values are expressed as median [interquartile range]. ICC, intraclass correlation coefficients between PET90 and PET45AI measures; MV, metabolic volume; CV, coefficient of variation; LLR, lesion-to-liver ratio
