Logan plot (reversible uptake model) result summary
Region of interest (n = 6) | AB distribution volume (ml) | PC distribution volume (ml) |
---|---|---|
Flank tumor | 1.13 ± 0.09 | 1.96 ± 0.15 |
Flank muscle | 0.77 ± 0.13 | 1.38 ± 0.23 |
Neck tumor | 1.21 ± 0.08 | 2.08 ± 0.13 |
Bone (femoral condyle) | 5.11 ± 2.19 | 13.47 ± 7.70 |
AB, arterial blood radioactivity used as input; PC, plasma-corrected (population-based metabolite-corrected fraction of the arterial blood radioactivity) used as input
Paired student’s t tests comparing distribution volume of tumors versus flank muscle (both AB and PC) and comparing AB inputs versus PC inputs were all significant (p < 0.003 and p < 0.00004, respectively)
