Parametric maps of the distribution volume ( V
) of [18F]NS14490 in the brain of piglets. Experiments were carried out under control (unblocked) conditions and with pre-treatment with the competitor NS6740 (blocked). Parametric maps are projected onto an MR atlas for the pig brain and represent the mean of (n = 4) control animals and (n = 3) animals with blocking. Data are given in mL g−1.
