volBrain was compared to the other two methods (corresponding interquartile interval is shown in brackets). Best results are in bold.
*
Indicates statistically significant differences between volBrain and Freesurfer (p < 0.05).
†
Indicates statistically significant differences between volBrain and FIRST. Overall represents the mean PVO of all structures excluding lateral ventricles to enable direct global comparison of the three methods.
