Idiopathic Scoliosis (AIS) is defined as a lateral spinal curvature greater
than 10 accompanied by vertebral rotation and has no clear underlying
causes. Traditionally AIS was evaluated using standing radiographs of the
full spine to assess lateral curvature with the Cobb method, but it is on 2D
coronal plane-only evaluating system, ignoring the 3D nature of AIS. MRI and
computer-generated 3D images is a noninvasive procedure which could be used
to assess the functional morphology in spine. To validate the hypothesis of
disproportional growth between neural and skeletal system a MRI study was
performed in 149 AIS patients and 41 age-matched controls.
