Fig. 4. A) Intracerebral TCO-polymer injection model B) confirmation of TCO-polymer retention by SPECT/CT C) averaged TACs and representative PET images showing in vivo uptake of 18F-Tzs in the left (TCO-injected) and right (TCO-free) striata. D) Absolute and relative contrast between left and right striatum for selected Tzs. PET images and contrast measurements are based on average 18F-activity uptake at 60–90 min post-injection.
