The application value of computer graphic imaging techniques in surgical scheme selection for upper urinary calculi / 实用放射学杂志

ABSTRACT

Objective To discuss the application value of computer graphic imaging techniques combined with CT urography in surgical scheme selection for upper urinary calculi.Methods 97 cases with complex upper urinary calculi underwent CT urography examination.The images were transferred by network to a separate workstation to perform volume rendering (VR),maximum intensity projection (MIP),multiplanar reconstruction (MPR) and curved planar reconstruction (CPR).All the post processing images were analyzed for selecting the appropriate surgical scheme.Results The 97 cases were treated properly according to their CT urography examination images,and all patients recovered without complications.Conclusion Urinary calculi and slight changes in the anatomical structure of upper urinary tract can be clearly demonstrated by computer graphics imaging techniques combined with CT urography,which may provide more information for disease diagnosis and selection of surgical scheme.
