TABLE I.
True activity | Measured activity (mean ± SD) | CoVa (%) | Percent activity errorb (%) | SUVc | |
---|---|---|---|---|---|
With positioner | 3.37 | 3.43 ± 0.15 | 4.37 | 1.75 | 1.02 |
Without positioner | 2.95 | 3.08 ± 0.042 | 1.36 | 4.22 | 1.04 |
CoV, coefficient of variation, i.e., image noise = SD/mean.
Percent activity error, i.e., recovery = (measured − true)/measured.
SUV, standardized uptake value = measured/true.
