Zusammenfassung
Background: The tgHD rat (von Horsten et al. 2003) carries 51 CAG repeats, which is within ranges observed in human genotypes. It was previously reported that small animal FDG-PET is able to detect hypometabolism in the whole brain of tgHD rats at 18–24 months of age. However, this initial imaging study was limited by its cross-sectional nature, the resolution of the small animal PET employed and the lack of a regional analysis. Due to the late-onset development of phenotype in tgHD rats compared to, e.g., the juvenile onset in R6/2 mouse, in-vivo imaging may facilitate phenotype assessment in therapeutic studie…
