A simple method for improving vertebral visualization on a scoliosis series lateral radiograph.
METHODS
This technical note describe a method for improving vertebral body visualization on lateral scoliosis radiographs.


OBJECTIVE
To improve vertebral column visualization on lateral radiographs.


BACKGROUND
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.


CONCLUSIONS
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.
