Impact of Endothelial 18-kDa Translocator Protein on the Quantification of 18F-DPA-714

Conclusion: Accounting for endothelial TSPO in the kinetic model improved the fit of PET data. The high correlation between Kb and TSPO mRNA suggests that the 2TC-1K model reveals more biologic information about the regional density of TSPO than the 2TC. The correlation between TSPO and endothelial cell mRNA supports the relationship between the regional variation of Kb and endothelial TSPO. These results can improve the estimation of binding parameter estimates from 18F-DPA-714 PET, especially in diseases that induce vascular change.
