多排螺旋CT低张力动态增强扫描在进展期胃癌术前评估中的价值

目的 探讨多排螺旋CT（MDCT）低张力动态增强扫描对进展期胃癌术前评估的价值.方法 对43例进展期胃癌患者行MDCT低张力动态增强扫描,判断肿瘤诊断及分期,预测手术可切除性,并与病理学结果进行比较.结果 本组43例行手术治疗,其中36例行手术切除,7例行肠胃吻合术.MDCT术前T分期总体符合率为76.7％（33/43）,术前N分期总体符合率为74.4％（32/43）.胃壁厚度与浆膜浸润密切相关（x 2=20.1709,P＜ 0.001）.结论 MDCT低张力动态增强扫描能够较全面、准确地反应进展期胃癌T、N分期,能够为胃癌术前诊断和治疗提供指导.

Value of multi-detector CT low tension dynamic enhanced scanning in preoperative evaluation of advanced gastric cancer

Objective To investigate the value of muhi-detector CT （MDCT） low tension dynamic enhanced scanning on the preoperative assessment of advanced gastric cancer.Methods MDCT low tension dynamic enhanced scanning,tumor diagnosis and staging and prediction of surgery operation were performed on 43 cases of advanced gastric cancer.And the above results were compared with pathology results.Results The 36 cases were treated with resection,while 7 cases were treated by gastrointestinal anastomosis.The MDCT had 76.7 % （33/43） of accuracy for the preoperative T staging and 74.4 % （32/43） of accuracy for the preoperative N staging,respectively.The stomach wall thickness was closely related to serosal invasion （x2 =20.170 9,P 〈 0.001）.Conclusions The MDCT low tension dynamic enhanced scanning can improve the comprehensiveness and accuracy of preoperative staging of T and N in advanced gastric cancer.It is valuable for the preoperative diagnosis and treatment of gastric cancer.
