仿真内窥镜CT和多平面重建对直肠癌术前分期的判断

目的：探讨CT仿真内镜（CTVE）和多平面重建（MPR）对直肠癌术前分期的判断。方法：通过系统地采用CTVE和MPR与普通CT对比，对45例直肠癌患者的分期进行了评估。结果：CTVE和 MPR术前分期的准确率为86.7%（39/45），普通盆腔CT为66.7%（30/45），两者间差异有显著性（P<0.05）。有淋巴结转移的术前准确判断敏感性CTVE和 MPR为76.9%（20/26），普通盆腔CT为50.0%（13/26），但差异有显著性（P<0.05）。结论：CTVE和 MPR对直肠癌进行临床分期的准确性较普通CT高，对临床治疗具有指导意义。

CT virtual endoscopy and multiple plane reconstruction in preoperative staging of rectal cancer

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.
