SUV_max/RPM-gated	87	0.66 ± 0.1 g/mL	0.00, 0.87 g/mL	<0.0005
SUV_max/ungated-matched	107	1.3 ± 0.2 g/mL	0.06, 2.0 g/mL	<0.0005
SUV_max/ungated-full	107	1.6 ± 0.2 g/mL	0.38, 2.0 g/mL	<0.0005
SUV_mean/RPM-gated	54	0.44 ± 0.1 g/mL	−0.01, 0.60 g/mL	0.003
SUV_mean/ungated-matched	64	0.97 ± 0.2 g/mL	0.01, 1.60 g/mL	<0.0005
SUV_mean/ungated-full	64	1.2 ± 0.2 g/mL	0.36, 1.59 g/mL	<0.0005
Lesion volume/RPM-gated	54	−0.30 ± 0.1 cm³	−0.52, 0.03 cm³	0.009
Lesion volume/ungated-matched	64	−0.70 ± 0.2 cm³	−0.98, −0.01 cm³	0.005

Data are mean differences (with SE on mean difference) and first and third quartiles, along with results from post hoc testing of transformed data. P values are uncorrected for multiple comparisons. Critical P value for statistical significance was 0.017 (lowered from 0.05 to allow for multiple comparisons).
