Scoliosis deformities progress more during skeletal growth, producing asymmetric loading. But the remaining question is why does scoliosis progress in some people but either does not progress or spontaneously corrects itself in others? We performed the first multi-parametric MRI acquisition in vivo on eight patients with adolescent idiopathic scoliosis. The results validated our hypothesis: T1rho, T2, MTR, ADC and FA within the intervertebral disc are modified in a specific way during scoliosis progression. The possibility to predict the evolution of the disc degeneration will allow a better target of the surgical or orthopaedic treatment than what is done today.
