Have you ever heard of stereoradiographic X-rays for scoliosis? We've already had a ton of regular X-rays taken. Do we really need more just because the technology makes it possible?

Stereoradiography is a technique for producing X-rays that give a three-dimensional view of an internal body structure (in this case, the spine). The stereoradiographs are taken with the patient in the standing position. Measurements of spinal shape including curvature and rotation can be made from all angles (side, front, top). The spinal axis system technology is advanced enough to make all of the spinal shape measurements digitally by using physical landmarks and three-dimensional coordinates. Stereoradiographic film studies of the spine are produced by combining two separate X-ray films. Each X-ray is taken from a slightly different angle. The developed films are then viewed through a device that allows the two images to be seen as one three-dimensional (3-D) object. Using this approach makes it possible for the surgeon to plan more carefully when surgery is needed. By visualizing every angle of the spine, curves and rotations of each vertebral body can be assessed ahead of time. There are even computer programs that allow the surgeon to try different surgical methods before applying it to the patient. This makes it possible to see which one would have the best results. If your region has stereoradiographic capability, this may be worth the extra time and money. But talk with your surgeon about what he or she sees as the advantage before making the final decision.
