Introduction: Previous statistical morphometric analysis of the brain MRI in Adolescent Idiopathic Scoliosis (AIS) patients and normal controls suggested there were statistically significant regional differences in the white matter.
Objectives: The aim of this study was to qualitatively and quantitatively identify the differentiation of the cortical thickness between the right-curve AIS patients and the age-matched normal controls.
Materials and Methods: The comparative study involved T1W MRI data acquired using FFE sequence on 20 right-curve AIS subjects and 20 age-matched normal controls. The white matter and pial surfaces were automatically segmented, from which the cortical thickness values were calculated. The Freesurfer software was applied to perform the cortical parcellation, cortical thickness calculation, and statistical analysis.
Results: Compared to normal controls, significantly increased thickness was detected in cortical surface of the right-thoracic AIS subjects around their middle parts of the superior frontal lobe in the left hemisphere (P<0.001).
Conclusion and Significance: The detected result implies the faster development in the superior frontal lobe in AIS subjects, which might be caused by their excessive attention and planning in their body movements. Moreover, it might also be associated with their emotional responses for not being socially acceptable as norms.
