Data from: Diffusion Tensor Imaging White Matter Atlas for the Domestic Feline

Abstract

The cat brain is a useful model for neuroscientific research and with the increasing use of advanced neuroimaging techniques there is a need for a white matter brain atlas to accompany the cortical grey matter atlas, currently available. In this article we document the creation of a feline white matter atlas from T1-weighted and diffusion tensor imaging (DTI) data obtained from a population of mesaticephalic felines. We provide T1-weighted, fractional anisotropy (FA), mean diffusivity (MD), apparent diffusion co-efficient (ADC), radial diffusivity (RD) and axial diffusivity (AD) population maps and created white matter tract priors from both deterministic and probabilistic tractography methods. These priors were created for the corpus callosum, fornix, cingulum, uncinate, corona radiata, inferior longitudinal fasciculus, interior fronto-occipital fasciculus and arcuate fasciculus and used to segment the data and document the mean and standard deviation of the diffusivity parameters for each tract. This represents the first and only feline brain atlas created from DTI data and will be a valuable resource for scientists doing anatomical, pathological and translational neuroimaging research in the feline model.
