Imaging modalities for the pediatric spine.

The role of MR imaging is emphasized in the evaluation of paraspinal and intraspinal soft tissue abnormalities. The technical aspects in performing a high-resolution MR image of the pediatric spine in reference to imaging parameters, sedation protocol, and the use of intravenous gadolinium are detailed. The changes in the normal pediatric spine on MR imaging are demonstrated. The diagnosis and evaluation of specific intraspinal and paraspinal neoplastic disorders in infants and children are outlined in terms of their clinical presentation and MR characteristics.
