Figure 5. 99mTc-TRODAT-1 uptake analyzed by SPECT imaging.

Figure 5

(A) Representative SPECT images for one monkey before (upper panels) and after (lower panels) MPTP treatment. The signal intensities in striatum were reduced after MPTP treatment. However, in the MPTP-treated animals, the right striatum showed higher signal intensities compared with the left striatum. The circled areas indicate the regions of interest. CB, cerebellum; OC, occipital cortex; Str, striatum. (B and C) The ratio of signal intensities in striatum relative to those in cerebellum and occipital cortex was measured (Str/[(CB + OC)/2]) before (B) and after (C) MPTP treatment. *P < 0.05, **P < 0.01.
