Table 4 Mean CRC values and CRC variation in comparison to PET100, considering the visible spheres pooled from the 3 experiments

From: Clinical and phantom validation of a deep learning based denoising algorithm for F-18-FDG PET images from lower detection counting in comparison with the standard acquisition

  PET100 PET50 PET50 + SP PET33 PET33 + SP
Mean (± Std Dev) CRC value 1.02 (± 0.25) 1.11 (± 0.28) 0.98 (± 0.26) 1.19 (± 0.30) 1.03 (± 0.28)
Mean variation (± Std Dev) versus PET100 9.3% (± 9,1%) − 4.1% (± 7.4%) 16.6% (± 12.6%) 0.3% (± 9.3%)
p value < 1.E4 0.02 < 1.E4 0.87
  1. p values of the paired t test between the CRC values for PET100 and the corresponding CRC for the 4 acquisitions/reconstructions are given
