Abstract To assess the value of three-dimensional (3D) image reconstructions of two-dimensional (2D) data from contiguous non-overlapping slices in the diagnosis of spinal trauma, 21 patients with a total of 36 injured vertebrae and 4 normal controls were examined. Forty plain films in two planes, 40 axial CT scans with multiplanar reformatted (MPR) 2D reconstructions and 40 sets of 3D images (surface rendering technique) were independently evaluated by four readers. The final diagnosis was defined after a panel review of clinical, surgical and imaging findings on all modalities. The 3D image reconstructions were not as accurate as axial CT with MPR 2D reconstructions in the diagnosis of vertebral body (n = 20) and posterior element fractures (n = 35). Dislocation (n = 3) was equally well detected by all imaging modalities. Narrowing of the spinal canal (n = 17) was best assessed by either MPR 2D CT or 3D images. A rotational component was diagnosed more accurately by 3D images, followed by 2D CT and plain films. Thus, 3D images combined with MPR 2D CT reconstructions are an important adjunct for an accurate diagnosis of spinal trauma, especially when a rotational component is suspected.
