Three-dimensional (3D) images were reconstructed from axial computed tomographic scans using the new 3D83 (General Electric Co.) software. Images were reformatted as a movie in multiple frames, each consisting of a discrete 3D scene, and were rotated 360° in 3D space. Improvement in shading and surface algorithm has been made from the previous 3D82 program so that 3D images now have a realistic appearance. Soft tissue and bone modes are available; the latter reconstructs best in 3D because of its high density pixels, which provide a more exclusive threshold. 3D reconstructions of the spine were the most rewarding because the complex anatomy of the spine seems to be best suited for 3D imaging. By hemisection of the spine by subregion, the intervertebral foramina can be evaluated for stenosis. Some drawbacks in this program are the need for user interaction, the lengthy time of reconstruction, and the dependence on high quality axial images.
