Abstract:
Objective To evaluate the methodology and the clinical usefulness of multi-slice helical CT virtual endoscopy(MSCTVE).Methods Twenty-six cases by suspected colorectal carcinoma underwent multi-slice helical CT virtual endoscopy after colon was cleaned and insufflated with air.The parameters were used:120 kV,250 mA,pitch 6,reconstructure thickness 2.5 mm,interval 1.0.All data sets were transferred to ADV 3.1 workstation,CTVE reconstruction were done with Navigator and used CTVE to view colorectal and rectum carcinoma.Of 26 cases,16 cases were proved by colonoscopy and 22 cases by operation.Results 14 cases carcinoma in rectum,8 cases in sigmoidcolon,1 case involved both rectum and sigmoidocolon.MSCTVE results were similar to colonography.Conclusion Multi-slice helical CT virtual endoscopy has clinical usefulness for detecting colorectal and rectum carcinoma as it is non-invasive,safe,feasible.MSCTVE is a supplement to colonoscopy especial in incomplete colonoscopy.
