Table 5 Effect of non-optimal filters on Δ SUVmax and Δ SUVref , for TOF1 and OSEM reconstruction protocols

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

Difference
threshold
Percentage with SUVmax (%) Percentage with SUVref (%) Percentage with non-optimal SUVref (%)
10% 78.4 34.4 38.0
20% 53.4 8.4 13.2
30% 32.0 1.4 3.4
  1. Percentage of hotspots with a Δ SUVmax or Δ SUVref greater than the specified threshold for the comparison of TOF1 and OSEM reconstruction protocols. Values are also shown when non-optimal SUVref filters are applied.
