Quantitative Accuracy of Low-Count SPECT Imaging in Phantom and In Vivo Mouse Studies
Figure 5
Correlation between SPECT measured results in MBq and ex vivo % ID measured in the gamma counter for tumours (a) and kidneys (b). There is a statistically significant correlation between the SPECT data and the biodistribution data which confirms the phantom results that the quantification is reliable at low activities.
