Brief Summary
The pathophysiology of adolescent idiopathic scoliosis is unknown. This pathology develops from 10-11 years of age and progresses until skeletal maturity, or even adulthood for the most severe forms. Current knowledge is limited as to its origin on the one hand and the evolutionary nature of scoliosis on the other. The mechanical parameters of the intervertebral disc are incompletely known from the deep location of this organ, its fragile nature in vivo and its susceptibility to desiccation during ex-vivo analysis. To complete our knowledge of the mechanical parameters of the intervertebral disc of scoliotic and non-scoliotic children, we are proposing an in vivo, non-invasive and non-irradiating study carried out in children who are the main target of this pathology. The objective of this work is to characterize the diffusion parameters (apparent diffusion coefficient ADC) of the intervertebral disc in vivo, in a non-invasive and non-irradiating manner by magnetic resonance imaging in children and adolescents. As this measurement has not been carried out in children and adolescents, we want to perform these MRI scans in children free from scoliosis and carriers of scoliosis.

Outcome Measures
Primary Outcomes (1)
measurement of the value of Apparent Diffusion Coefficient (ADC) in magnetic resonance imaging.
between Day 15 and Day 90
Secondary Outcomes (3)
Apparent Diffusion Coefficient difference for scoliosis and non-scoliosis patients for one level
between Day 15 and Day 90
Correlation between right and left Apparent Diffusion Coefficient and inclination of two vertebra for scoliosis patients
between Day 15 and Day 90
gagCEST(Chemical Exchange Saturation Transfer) measurement in magnetic resonance imaging of the discs
between Day 15 and Day 90
Study Arms (2)
Scoliotic patients
children with spinal deformity characterized by a hump on clinical examination and a radiological deformation in the coronal plane greater than 10 ° .
Non scoliotic patients
Childrne with no hump on clinical examination, able to walk.
Interventions
The duration of the acquisition sequence between 2 and 10 minutes additional compared to a conventional magnetic resonance imaging examination.
Eligibility Criteria
children and adolescents with and without scoliosis seen in consultation and requiring magnetic resonance imaging of the lumbar region
You may qualify if:
- age: patients between 8 and 16 years old
- Children undergoing magnetic resonance imaging of the lumbar or spinal region as part of their routine care
- Scoliotic: spinal deformity characterized by a hump on clinical examination and a radiological deformation in the coronal plane greater than 10 ° with no etiology found (idiopathic)
- Healthy: no hump on clinical examination, walking patients (level 1 and 2 of the global motor function classification system)
You may not qualify if:
- existence of medullary and vertebral pathology other than scoliosis, history of disc or vertebral infection (spondylo-discitis) on examination, neuro-ectodermal pathology
- behavioral disturbances incompatible with the performance of the magnetic resonance imaging examination.
- Refusal of participation.
- Thoracic scoliosis
