Table 1.

Regional distribution of specific binding (distribution volume ratios (DVR) relative to cerebellum) for (±)-[18F]fluoroethylDTBZ (FE-DTBZ), (±)-[18F]fluoropropylDTBZ (FP-DTBZ), and (+)-[11C]DTBZ in the rat brain. Data are mean ± standard deviation with N = 4 for each FE- and FP-DTBZ, and N = 35 for DTBZ. Data for [11C]DTBZ from reference [14]. nd = not determined.
