Quantification of cortical folding using MR image data

Robert Wright, Daniel Rueckert, Paul Aljabar, Engineering And Physical Sciences Research Council
2016
Premature birth is a high risk factor for poor neurodevelopmental outcome and has been associated with abnormal cortical development, however the nature of the disruption to developmental processes is  ...  Displacement patterns were revealed which intensified with increasing prematurity, however more work is needed to evaluate the reliability of these findings.  ...  A spectral analysis yields spatial correspondences between a group of cortical surfaces, allowing the average surface position to be computed and a template surface constructed.  ...

The clinical assessment scores were compared between the groups by analysis of variance (ANOVA), followed by post hoc comparisons (Tukey-Kramer HSD). The level of significance was set at p < 0.05.  ...  The 13 items of the ABC-DS are grouped into three domains: domain A, related to ADL function; domain B, related to BPSD; and domain C, related to cognitive function, and the ABC-DS uses a 9point scale  ...  Structural brain measurements included cortical thickness, local cortical gyrification, and cortical and subcortical volumes in 47 brain regions. Gyrification is an index of deepness of sulci.  ...
