Piglet MRI Atlas Collection

This includes the MRI data sets of the averaged brain for the 4-week old piglet, prior probability maps, and regions of interest files

Comparison of an individual MRI data set and the atlas.

<p>The axial slices are from −18 mm to 18 mm in 6 mm increments. The top row is a representative individual case and the bottom row is the atlas.</p

Tissue probability maps.

<p>Coronal slices through the origin showing the atlas T1 image, gray matter, white matter, and cerebrospinal fluid (CSF) tissue probability maps. The maps have been smoothed with a 1 mm FWHM Gaussian filter.</p

Fractional anisotropy (FA) values for AGA and SGA piglets.

<p>The FA value determined from Diffusion Tensor Imaging was lower in SGA piglets compared to AGA piglets (*p = 0.04). Data are shown as the mean ± SEM (n = 5).</p

Voxel-based morphometry analysis of Gray Matter and White Matter differences in the SGA and AGA piglet brains. Non-parametric permutation tests were used with a threshold of p<0.01 uncorrected and a minimum cluster size of 20 voxels.

<p>*X increases from left (-) to right (+), y increases from posterior (-) to anterior (+), and z increases from inferior (-) to superior (+).</p><p>** Based on estimates from adult brain atlas. PVC- primary visual cortex, AVC-associated visual cortex, SVC- secondary visual cortex, PSC- primary somatosensory cortex.</p

Voxel-based morphometry analysis using DARTEL showed increased gray matter volumes in the olfactory bulb and cortex of SGA piglets.
