NSD_hypothalamus_atlas

This study describes a high-resolution in-vivo magnetic resonance imaging atlas of the human hypothalamus.<br> <br> We employed a minimum deformation averaging (MDA) pipeline to produce a normalized (MNI152b), high-resolution template from multimodal (T1w and T2w) magnetic resonance imaging (MRI) datasets. 990 subjects derived from the HCP1200 date release were included in this study.<br> This template was used to delineate hypothalamic (n=13) and extrahypothalamic (n=12) gray and white matter structures.<br> <br> Files (in bold) of the hypothalamus atlas segmentation (tables (.csv) and images (nifti format)):<br> -a table with the structure name, abbreviation and label number:<br> <strong>Volumes_names-labels.csv</strong><br> -the full volume segmentation in 0.25 and 0.5 millimeter isotropic resolution:<br> <strong>atlas_labels_0.25mm.nii.gz</strong><br> <strong>atlas_labels_0.5mm.nii.gz</strong><br> -an archive of binary images of each structure separately:<br> <strong>isolated_nuclei_0.25mm_resolution.zip</strong><br> <br> The high-contrast, high-resolution MDA template images in 0.25 and 0.5 millimeter isotropic resolution:<br> <strong>MDA_990HCP_t1_MNI152b_0.25.nii.gz<br> MDA_990HCP_t1_MNI152b_0.5.nii.gz<br> MDA_990HCP_t2_MNI152b_0.25.nii.gz<br> MDA_990HCP_t2_MNI152b_0.5.nii.gz</strong><br> <br> Tables that describe the average structure volumes in the subjects used to generate the MDAs:<br> <strong>Average_left_right_hemispheric_hypothalamic_volumes_by_Sex.csv<br> Average_left_right_hemispheric_hypothalamic_volumes.csv</strong> <strong>Estimated_volumes_of_hypothalamus_proper_its_divisions_and_nuclei.csv</strong> Authors: Clemens Neudorfer, Jürgen Germann, Gavin J.B.
