Qualitative Image Quality Score and Quantitative Parameters in the Ultra-Low-Activity Group and Full-Activity Group
| Parameter | G8 | g2 | P |
|---|---|---|---|
| Image quality score | 3.91 ± 0.30 | 3.82 ± 0.60 | 0.311 |
| Lesion SUVmax | 23.43 ± 8.64 | 24.22 ± 12.15 | 0.863 |
| Liver SUVmax | 3.39 ± 0.54 | 3.17 ± 0.55 | 0.354 |
| Liver SUVmean | 2.78 ± 0.33 | 2.84 ± 0.47 | 0.747 |
| Liver SD | 0.21 ± 0.05 | 0.23 ± 0.08 | 0.544 |
| TBR | 7.07 ± 2.74 | 7.56 ± 3.51 | 0.738 |
| SNR | 13.77 ± 2.14 | 13.40 ± 2.90 | 0.716 |
Data are presented as mean ± SD. Mean value and SD were calculated on basis of Likert score for each patient. Mean value and SD of other quantitative parameters were calculated on basis of measurement in ROIs.
