Table 3 Patient liver noise

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

Liver COV (%) OSEM TOF HD UHD
Matched COV 10.6 (2.3) 10.5 (2.4) 10.6 (2.2) 10.4 (2.1)
Matched SUVmax 9.5 (2.1) 6.8 (1.5) 5.9 (1.3)
  1. Image noise, expressed as coefficient of variation (COV), measured in the liver for each reconstruction for matched voxel COV and matched SUVmax post-filters. Values are mean and standard deviation, with the latter shown in parentheses.
