摘要
目的:回顾65例直肠癌多层螺旋CT影像特点及影响因素,以提高多层螺旋CT对直肠癌的诊断及术前分期水平。方法:直肠病变患者进行灌肠MSCT扫描,由两名主治医师以上人员进行诊断,并随访术中的大体病理。结果:直肠癌的MSCT表现为直肠壁局限性增厚23例,直肠壁环形增厚及变窄15例,直肠肿块27例(单纯突向腔内肿块17例,合并突向腔外突出肿块10例),相邻脏器直接侵犯或远处转移征象30例。影响因素主要为粪块2例、肠管充盈不良3例及未检查远处脏器转移1例。结论:直肠癌术前进行MSCT检查不仅可以定位,还可以明确病变的大体病理类型、病灶浸润深度及范围、有否侵犯邻近脏器和远处转移,以便临床分期。以制定相应的手术方式,提高患者术后的生存率。
Objective： To investigate the features of rectal carcinoma in multi-slice spiral computed tomography（MSCT）. Methods： The imaging findings of MSCT in 65 patients with rectal carcinoma were analyzed retrospectively. Results： Local thickening of the rectal wall were found in 23 case, ring thickening of the rectal wall in 15 cases, issue mass in 27 cases （including only extrude into the inner of the rectum in 17 cases, extrude into inner and outer of the rectum in 10 cases）. Stoolmass was found in 2 cases, the rectum was filled insufficiently in 3 cases and 1 case of distant metastasis not detected. Conclusion： MSCT can clearly demonstrate not only the tumor site, but also the gross morphology, involved depth and distant metastasis. Good bowel preparation and multi-planar reconstruction is necessary for MSCT.
