FIGURE 7. SPECT quantification obtained from postmortem images vs. ex vivo activity concentration for eight pigs included in study.
= activity concentration measured in every myocardial segment with only attenuation correction applied. Dashed line is least-squares linear fit to data with slope of 0.402 and offset of 7.53 kBq/g (r = 0.776).
= activity concentration measured in every myocardial segment with both attenuation and partial-volume corrections applied. Solid line is least-squares linear fit to data with slope of 0.877 and offset of 16.72 kBq/g (r = 0.876).
