Radiography remains the mainstay of diagnosis and evaluation of scoliosis, giving the ability to image the entire spine in the standing patient in order to appreciate the scoliotic deformity. Standing radiographs allow more reliable radiographic measurements that are important in following the magnitude of the spinal deformity over time and ultimately in surgical decision-making. The radiographic analysis of curvatures may include sideward-bending views and flexion–extension views. To date, one anteroposterior (AP) and one lateral (LAT) scoliosis x-ray images are generally performed, with systematic radiographic imaging...

Two systems are used to perform full spine studies at our paediatric hospital, a General Electric Definium 8000 (GE) and a new system, Fuji FDR Smart Suspension, with a FDR-D-EVO-GL detector, which allows performing full spine images in one shot.The detector consists of three regular detectors placed together (Figure 1), so there is no need to move the x ray tube and detector down the spine, nor to overlap or image pasting, thus reducing artefacts and presumably patient effective doses due to non-overlapping. [Fig 1]73...

Patients from the GE unit were categorised by age and also by number of images. In the [10, 14) category, 34 patients were included. 64.7% of those patients received a two image acquisition (22 patients), and 35.3% (12 patients) were subjected to a 3 image acquisition. In the [14, 18) category, as opposed, 70% of the patients received 3 images (27 patients) and 30% just two images, as the mean size in this category is larger.Figures 4 and 5 show the mean effective dose estimated...

One-exposure system allows optimization of patient doses, but the especially interesting aspect of this device is that it has a strong potential for reducing reconstruction and movement artifacts, with the subsequent decrease of repeated images. An analysis of image repetition rates in both units would reinforce these optimistic results.
