Binding potential values. The test and retest mice (n = 5) received 1.12 ± 0.08 MBq/g b.wt. and 0.94 ± 0.07 MBq/g b.wt. of 123I-β-CIT, respectively. Mice were imaged with the equivalent protocol in the test and retest time points; scanning length was 25 min (angular step 15°, 24 projections, 250 s per gantry position). The data were acquired in a 128 × 128 matrix with pixel size and a slice thickness of 0.2 mm. Individual BP values were obtained at 4 h postinjection on each of the five mice at both test and retest (8 days later), with the corresponding mean and standard deviation. The test-retest measurements were insignificantly different (P = 0.968).
