Motion artefacts with the EOS 2D system. Lateral views of the lumbar spine in a 7-year-old boy suffering from an anterior spondylolisthesis of L5 related to a pars interarticularis defect are shown. Child’s movement during the image acquisition (on the left) is responsible for a distorted aspect of the spine and the proximal femurs (arrows). Compare with another lateral view in the same patient without artefacts (on the right). [Total DAP = 140 mGy·cm2]
