Abstract:

BACKGROUND: Multislice spiral CT has become an effective tool for imaging diagnosis of bone tumors, the advantages of fast scanning speed, clear image and less radiation make it possible of the large-scale three-dimensional scanning.
OBJECTIVE: To investigate the application value of multislice spiral CT combined with three-dimensional reconstructed post-processing techniques for the diagnosis of bone tumors.
METHODS: Wanfang database was searched by the first author for the articles on multislice spiral CT and post-processing techniques for the diagnosis of bone tumors from 1995 to 2011. Key words were “image processing, bone tumors, tomography, three-dimensional post-processing, X-ray computer” in Chinese. According to the inclusion criteria, the articles on the three-dimensional reconstruction of bone tumors with highly direction and correlation were included, as well as the articles on the application of maximum intensity projection, surface shaded three-dimensional reformatted images and volume rendering technique in the diagnosis of bone tumors. Repetitive studies, published earlier, review and Meta analysis were eliminated. Finally, a total of 20 articles were included to review according to the inclusion criteria after the primary search.
RESULTS AND CONCLUSION: Each reconstructed image can display the bone tumors; the multi-planar reconstructed image can accurately display the bone destruction, periosteal changes, the scope of bone destruction and violation of tumor to the surrounding soft tissue. Maximum intensity projection, surface shaded three-dimensional reformatted images and volume rendering technique can volumetric display the changes of the bone; enhanced surface shaded three-dimensional reformatted images and volume rendering technique can show the tumor feeding arteries, vein and tumor vessels. Post-processing combined with cross-sectional images can accurately show the bone destruction, periosteal reaction type, the extent of the tumor and violation of tumor to the surrounding soft tissue from different directions.
