Table 5 Relative uptake differences for matched SUV max recovery

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 +5.4% +0.6% +5.3%
  95% CI −8.5% to +19% −8.1% to +9.4% −9.5% to +20%
  n > 25% change 1/74 0/74 2/74
SUVpeak Mean% change +5.3% +1.7% +6.3%
  95% CI −6.4% to +17% −3.0% to +6.5% −4.9% to +17%
  n > 30% change 0/74 0/74 1/74
TLG-40 Mean% change +3.8% +2.4% +4.0%
  95% CI −13% to +20% −13% to +18% −12% to +20%
  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 SUVmax.
