Integral of the SUV activity (0 – 60 min) for the different methods, as well as Bland–Altman analysis of IDIF and NMF-IDIF with respect to AV-shunt measured activity

	Activity integral (SUV∙min)	Bland-Altman bias $\pm$ SD (%)	95% limits of agreement
AV-shunt	29.6 $\pm$ 2.8
IDIF	42.9 $\pm$ 3.1	+ 35.7 $\pm$ 5.94%	+ 47.4 – 24.1%
NMF-IDIF	37.5 $\pm$ 4.3	+ 22.2 $\pm$ 3.28%	+ 28.6 – 15.8%
