Abstract:
Objective To study the value of 3D-CT reconstruction in the diagnosis of surface involved lesions of bone for its nature and location,comparing with plain film and 2D-CT.Methods Surface-involved lesions of bone revealed by plain-film were performed spiral CT examination.Multi-planar reconstruction(MPR)and surface shading display(SSD)were performed among 20 cases which had pathologic results.The diagnosing correct rate of nature and location in all the techniques were compared.Results The correct rate of nature diagnosing of plain film,2D-CT,MPR and SSD was 75%,80%,65%,60% respectively;correct rate of location diagnosing was 90%,75%,85%,95% respectively.The highest nature diagnostic correct rate was found in 2D-CT.The highest location diagnostic correct rate was found in SSD.Conclusion Spiral CT stereoscopic reconstruction is of great value in the location diagnosing of surface-involved bone lesion.
