| pubmed-article:10211204 | pubmed:abstractText | This study concerns the estimation of the artifacts introduced by the metallic frame of an Ilizarov apparatus during quantitative computed tomography for the assessment of neoosteogenesis. Ten cadaver tibiae were tomographed before and after the mounting of an Ilizarov device. The increase in mean density and in the relative number of pixels were used as indicators of the artifacts induced by the apparatus. No significant influence by the device was recorded in regions corresponding to a corticotomy site. In regions close to the metallic rings of the Ilizarov apparatus, measurements are distorted significantly, but with no influence on the assessment of neoosteogenesis. | lld:pubmed |
