Abstract：Objective: To evaluate value of postprocessing of 64 slice MSCT reconstruction techniques in diagnosing malignant tumors of long bone. Methods: Reconstruction techniques were used after 64-slice CT imaging had been completed for 52 patients with long bone tumors. Based on the raw data, two kinds of image reconstruction, including multiple planar reconstruction(MPR) and volume rendering(VR) were carried out. Results: All reconstructed images showed bone tumor. MPR accurately displayed bony damage, changes in periosteum, extent of bony damage and tumor invasion to surrounding soft tissues; VR displayed changes in bone stereographically; VR on basis of enhancement, displayed supplying arteries, veins and neoplastic blood vessels. The two techniques combined with cross-sectional images were able to display bony damage, type of periosteal reaction, extent of tumor and invasion of tumor to surrounding tissues along different axes. Conclusion: The two kinds of 64-slice CT postprocessing images can fully and accurately demonstrate the malignant tumors of long bone, combined with the axial images correct evaluation of the malignant tumors of long bone can be made.
