↵* Calculation based on S/C-1 ratios.
Data were obtained from baseline small-animal PET imaging of 18F-JNJ41510417 and from pretreatment self-blocking and blocking experiments with TP-10 and MP-10. S/C-1 ratios are averaged values from 32 min after tracer injection (when maximum is reached) until 75 min after tracer injection (when S/C-1 ratio starts decreasing). Data are expressed as mean when n > 1.
