Three-dimensional Ct Study Of Brain Lesions

Images offered by conventional diagnostic tools for skull and intracranial lesions, including X-ray film, angio-graphy, ventriculography, CT, MR, and PET, are usually two dimensional. As the human body and pathological lesions are really solids of three dimensions, observers have to reconstruct a mental image of three dimensions from two dimensional visual informations. This may be difficult in some cases even misleading.Recent developments in computer software make it possible to reconstruct three dimensional pictures from a series of conventional CT sections and has already been applied to crainofacial, musculoskeletal and intracranial abnormalities,In this study, 3DCT images were reconstructed from trans-axial CT scanning with the aids from 3D98 software in 133 patients with skull and intracranial lesions, 6 dry skulls and 6 models of diease.The characteristics of images are: 1.The 3DCT images obtained from the 3D98 software are accurate and realistic;...
