Abstract
Study Design This technical note describes a method for improving vertebral body visualization on lateral scoliosis radiographs. Objective To improve vertebral column visualization on lateral radiographs. Summary of background Data The different densties of the thoracic and abdominal cavities makes complete visulization of the vertebral column difficult on laterl radiographs. Methods An inexpensive, simple filter paper method was used to normalized the densities between adjacent body cavity and improve visualization of the vertebral column on a lateral scoliosis series radiograph. Results Use of a single-exposure, filter paper technique improved simultaneous visualization of the tharacic and lumbar vertebrae, compared with the standard single-exposure, unifiltered technique. Conclusion Accurate lateral vertebral visualization allows effective three-dimensional correlation of the sagittal plane deformity concurrent with the coronal plane deformity of socoliosis. Using a single-exposure filter paper technique improves sagittal plane spinal visualization. Repeat radiographs and patient exposure are reduced by this technique.
