A Simple method for Improving Vertebral Visualization on a Scoliosis Series Lateral Radiograph

STUDY DESIGN: This technical note describe 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 density of the thoracic and abdominal cavities makes complete visualization of the vertebral column difficult on lateral radiographs. METHODS: An inexpensive, simple filter paper method was used to normalize 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 thoracic and lumbar vertebrae, compared with the standard single-exposure unfiltered technique. CONCLUSION: Accurate lateral vertebral visualization allows effective three-dimensional correlation of the sagittal plane deformity concurrent with the coronal plane deformity of scoliosis. Using a single-exposure, filter paper technique improves sagittal plane spinal visualization. Repeat radiographs and patients exposure are reduced by this technique.
