Linear Regression Fitting and Correlation Between BP_ND Obtained Using Full Tracer Kinetics (BP_ND,2TC) and BP_ND Obtained Using Noninvasive Models or SUVR − 1

Noninvasive kinetic model	Acquisition protocol (min)	Interpolation	Intercept	Slope	R²
MRTM2	0–140	None	−0.01	0.77	0.86
	0–30/120–140	Average time–activity curve	0.00	0.80	0.82
SRTM	0–140	None	−0.01	0.77	0.72
	0–30/120–140	Average time–activity curve	0.02	0.72	0.74
SUVR − 1	120–140	None	0.04	0.99	0.87

Full tracer kinetics use arterial blood sampling (2-tissue-compartment model [2TC]). For noninvasive models, BP_ND = slope + intercept ⋅ BP_ND,2TC. SUVR − 1 = slope + intercept ⋅ BP_ND,2TC.
