Abstract

We investigated the diagnostic value of 3-D-surface reconstruction techniques in lumbar spinal CT and compared the postprocessed pictures to axial CT scans and conventional X-rays in 50 patients. All of our patients suffered of backache without showing evidence of intervertebral disc herniation in axial CT. Before the examination we tested the accuracy of the Siemens Somaris software program, by measuring a 1:1 scaled reconstruction of a polyethylene model of L3. After this the reconstructions were done with a threshhold of 150 H.U. using the integral shading programm. The bone surface was photographed in 4 standard pojections (anterior, posterior, lateral left and lateral right) as well as in mediosagittal and coronal cuts. All of these were compared to the axial CT and radiographs.
