Table 1. Comparison of average of SUVmax and SUVmean according to the qualitative BPE grade.

SUV	Minimal (n = 52)	Mild (n = 86)	Moderate (n = 133)	Marked (n = 27)	p-value
SUVmax	1.42 ± 0.34	1.59 ± 0.47	1.82 ± 0.40	2.06 ± 0.31	< 0.001
SUVmean	0.87 ± 0.21	0.97 ± 0.21	1.14 ± 0.25	1.32 ± 0.21	< 0.001

Data are presented as mean±SD.

SUV=standardized uptake value; BPE=background parenchymal enhancement.
