title: [Imaging of scoliosis].
abstract: The majority of scoliosis (80%) and especially the idiopathic scoliosis are simply investigated by plain films of the entire spine with erect frontal and lateral views, and supine frontal view at the initial examination. Repeated erect frontal views are sufficient for the follow-up. The important radiation dose (average of 1.2 mG for the frontal view and 2.2 mG for the lateral views) imposes to reduce the frequency of these radiographs. This radiological study allows: to separate non structural and structural curves; the identification and the measurement of a structural curve, discussion for its etiology, appraisal of its progressiveness, discussion of the operative or non operative treatment, and radiological follow-up. Modern imaging (C.T, C.T myelography, MRI) is indicated only in very particular cases: idiopathic scoliosis with neurological symptoms, congenital scoliosis with structural vertebral abnormalities, especially these with posterior arch abnormalities, and progressive scoliosis in spinal dysplasiae. Painful scoliosis are unusual. If pain is present consideration should be given for diagnosis of an underlying lesion. In this case a relevant strategy using modern imaging becomes useful and will be discussed.
