Distribution of Δ
with non-optimal filters for PSF and OSEM reconstruction protocols. Δ
SUVmax (solid line) and Δ
SUVref (dashed line). The mean (and SD) for Δ
SUVmax was -20.3% (9.1) and for Δ
SUVref -1.00% (3.54). Also shown with a dotted line is the distribution of Δ
SUVref with the application of suboptimal filters. The mean (and SD) for this non-optimal Δ
SUVref is -6.25% (3.89). The difference between each distribution is significant (P < 0.001 with paired two-tailed Student's t test).
