Gousias IS, Hammers A, Heckemann RA, Counsell SJ, Dyet LE, Boardman JP, Edwards AD, Rueckert Det al., 2010, Atlas selection strategy for automatic segmentation of pediatric brain MRIs into 83 ROIs, Pages: 290-293

Registration algorithms can facilitate the automatic anatomical segmentation of pediatric brain MR data sets when segmentation priors (atlases) are in hand. Automatic segmentation can be achieved through label propagation and label fusion in target space. We investigated the performance of different age cohorts used as prior atlases for the segmentation of 13 MRIs of 1-year-olds. Thirty adults and 33 2-year-olds (including the 13 1-year olds, scanned a year later) served as priors for label propagation and fusion. In addition, we tested the accuracy of a single propagation step of the atlas of the same subject scanned at 2 years of age. Pediatric priors performed better than adult priors on visual inspection as well as manual validation of the caudate nucleus (Dice index=0.89±0.02 vs. 0.86±0.03). Corresponding single atlases at the age of 2 performed better than the fusion of 30 adult priors (83 ROIs / average Dice=0.87±0.05 vs. 0.84±0.07). © 2010 IEEE.
