Distribution of Δ _SUVmax and Δ _SUVref with non-optimal filters for TOF1 and OSEM reconstruction protocols. Δ _SUVmax (solid line) and Δ _SUVref (dashed line). The mean (and SD) for Δ _SUVmax was -23.4% (17.2) and for Δ _SUVref 1.23% (11.2). 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 -5.69% (12.1). The difference between each distribution is significant (P < 0.001 with paired two-tailed Student's t test).
