摘要
目的 探讨螺旋CT不同的扫描方法对胃癌分期的价值。资料与方法 进展期胃癌 2 32例进行螺旋CT扫描 ,其中门静脉单期增强 84例 ,三期增强 96例 ,人工气腹法螺旋CT增强 (SCTPP) 5 2例。结果 门静脉期单期增强、三期增强和SCTPP对进展期胃癌TNM分期准确性分别为 75 .0 %、82 .3%和 96 .2 %。结论 胃癌术前分期首选螺旋CT三期增强 ,若仍无法准确评估分期的体瘦患者可选用SCTPP ,术后复查首选螺旋CT门静脉期单期增强。
Objective To study spiral CT scanning technique used in staging gastric carcinoma.Materials and Methods Preoperative spiral CT scanning was performed in 232 patients with advanced gastric carcinoma, of which single phase portal enhancement scanning was carried out in 84, tri phase enhancement scanning in 96, and artificial pneumoperitoneum enhancement scanning in 52.Results TNM staging accuracy of advanced gastric carcinoma for the above mentioned three scanning techniques in order was 75.0%, 82.3% and 96.2%, respectively.Conclusion For preoperative staging of gastric carcinoma, spiral CT tri phase enhancement scanning is of choice. Artificial pneumoperitoneum enhancement scanning can be used for thin patients when staging can not be accurately evaluated by tri phase enhancement scanning. For postoperative checkups, single phase portal enhancement scanning is recommended.
