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.
