Table 4 Relative uptake differences for matched voxel COV

From: Impact of point spread function modelling and time of flight on FDG uptake measurements in lung lesions using alternative filtering strategies

Uptake   TOF HD UHD
SUVmax Mean% change +8.8% +32% +49%
  95% CI −7.2% to +25% +7.8% to +55% +1.0% to +97%
  n > 25% change 4/74 50/74 63/74
SUVpeak Mean% change +6.9% +17% +27%
  95% CI −5.7% to +20% +5.3% to +29% +1.6% to +51%
  n > 30% change 1/74 1/74 25/74
TLG-40 Mean% change +1.9% −8.4% −7.5%
  95% CI −16% to +20% −29% to +12% −37% to +22%
  1. Mean percentage changes and 95% confidence intervals of the three uptake measures relative to OSEM reconstruction. Also shown are the number of lesions with a greater than 25% and 30% increase in SUVmax and SUVpeak, respectively. Data in the table are from images using post-filters to match image voxel COV.
