Objective:To investigate the value of CT virtual endoscopy(CTVE) and multiple plane reconstruction(MPR)for preoperative staging of rectal cancer. Methods:Fortyfive patients with rectal cancer were examined by CTVE and MPR to determine the preoperative staging,and the reselts were compared with CT.Results:For evaluation of intramural invasion,the accuracy rate of CTVE and MPR was 86.7%(39/45),pelvic CT was 66.7%(30/45)(P<0.05).For lymph node involvement,the accuracy of CTVE and MPR was 76.9%(20/26),pelvic CT was 50%(13/26)(P<0.05). Conclusions:For preoperative staging of rectal cancer, the accuracy rate of CTVE and MPR was higher than that of pelvic CT. CTVE and MPR is of important significance in guiding clinical treatment.
