Table 4 Effect of non-optimal filters on Δ SUVmax and Δ SUVref , for PSF and OSEM reconstruction protocols

From: SUVref: reducing reconstruction-dependent variation in PET SUV

Difference threshold Percentage with SUV max (%) Percentage with SUV ref (%) Percentage with non-optimal SUV ref (%)
10% 93.2 1.4 12.6
20% 44.6 0.6 0.8
30% 12.2 0.0 0.0
  1. Percentage of hotspots with a Δ SUVmax or Δ SUVref greater than the specified threshold for the comparison of PSF and OSEM reconstruction protocols. Values are also shown when non-optimal SUVref filters are applied.
