Preclinical MRI has become a promising technique to examine mouse brain morphology. In this study, we employed an optimised sequence for high resolution 3D in vivo imaging. We used a novel automatic image analysis toolbox to examine a mouse model of Alzheimers disease (rTg4510). Tensor-based morphometry analysis revealed significant changes in local brain volume between this model and age-matched wild-types. Our findings correspond to expected changes, including hippocampal and forebrain atrophy, as well as ventricular dilation.
