Total	11	10	50	53
SUV max	1.79 ± 0.46^*	9.85 ± 7.58^*^†	3.48 ± 0.91^*	6.61 ± 4.12^†
Impurity number (%)	0 (0%)	7 (70%)	9 (18%)	42 (79%)
Percentage symmetry {100% × \|SUV_R – SUV_L\| ÷ ([SUV_L + SUV_R]/2)}	14.4 ± 8.0	36.2 ± 21.1^†	17.1 ± 14.3	30.8 ± 21.8^†

↵* ANOVA with Tukey post hoc test, P < 0.05, different from metastatic-disease group (average ± SD or number of patients (%)).
↵† ANOVA with Tukey post hoc test, P < 0.05, different from benign and no-metastatic-disease groups.
