Figure 4From: SUVref: reducing reconstruction-dependent variation in PET SUV Distribution of Δ SUVmax and Δ SUVref 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).Back to article page
