Recent advances in MRI have produced high-contrast imaging of the hippocampus. In this work, we use a population of 195 atlases based on T1-weighted MR images with the left and right hippocampus delineated into the head and body. We initialize the multi-atlas segmentation to each lateralized hippocampus to both speed up and improve the accuracy of registration. The segmentation results in a Dice similarity coefficient over 0.9 for the full hippocampus. The head and body delineation resulted in a Dice coefficient over 0.87 for both structures.<\/p>\n<p>&nbsp;<\/p>\n<figure id=\"attachment_1064\" aria-describedby=\"caption-attachment-1064\" style=\"width: 2576px\" class=\"wp-caption alignnone\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-1064\" src=\"https:\/\/my.vanderbilt.edu\/masi\/wp-content\/uploads\/sites\/2304\n2661\/2017\/02\/SPIE_OVAL_Poster_v1_ap.jpg\" alt=\"Qualitative segmentation results. \" width=\"2576\" height=\"1126\" \/><figcaption id=\"caption-attachment-1064\" class=\"wp-caption-text\">Qualitative segmentation results.<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Andrew J.
