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 investigate the value of different spiral CT scan methods in gastric cancer staging. Materials and Methods 2 32 cases of advanced gastric cancer underwent spiral CT scan. Among them, 84 cases were portal venous enhancement, 96 cases were enhanced in the third phase and 52 cases were spiral CT enhanced by artificial pneumoperitoneum (SCTPP). Results The portal venous phase single-phase enhanced, triple-phase enhanced and SCTPP advanced gastric cancer TNM staging accuracy were 75.0%, 82.3% and 96.2%. Conclusion The preoperative staging of gastric cancer preferred helical CT enhanced third, if still can not accurately assess the staging of patients with lean body may choose SCTPP, postoperative review preferred spiral CT portal venous phase single-phase enhanced.
