Abstract: Objective To discuss the clinical value of application of three-dimensional reconstruction technique of MSCT in examination of colonic tumours.Methods Thirty patients underwent scanning using helical CT and post-processing on the workstation.All CTC images were reconstructed using shaded surface display (SSD) on workstation.Perspestive images such as the ones from DCBE were generated via raysum.The images could clearly demonstrate the extent and detail of the disorder by adjusting the CT value threshold.These results and that of barium enema and colon endoscopy were compared.Results Thirty cases had completely clinical and pathological data.3D images could correctly reveal the macroscopic morphology of colon tract and location of lesions.The correctly diagnostic rate was 100％ by MSCT,while the diagnostic rate by CTVE and colon endoscopy was basicly identical.Conclusion With the utilization of multiple methods,3D reconstruction can effectively demonstrate colonic tumours,and can be applied routinely in examination of colonic tumours.
