Zusammenfassung
Ziele: To evaluate the feasibility of micro-CT for analysis of primary, non-haematopoetic human bone tumors. Methode: Samples from12 human bone specimen (osteosarcoma n=6; chondrosarcoma n=6) obtained for diagnostic purpose were scanned using industrial x-ray film without amplifier foil and scanned with micro-CT (7 and 12µm cubic voxels). Trabecular bone CT “density“ and tumor matrix CT “density“ were determined and results were compared with those obtained from a detailed conventional histopathologic analysis of corresponding cross-sections. The significance of differences in gray scale measurements was tested…
