摘　　要：目的:评价低张力口服水多层螺旋CT(MSCT)3期扫描对进展期胃癌的诊断、分期及可切除性判断的价值。方法:65例患者口服水,在低张状态下进行动态增强扫描。判断肿瘤诊断及分期,预测手术可切除性,并与手术及病理相对照。结果:本组病例52例行手术治疗,13例MSCT评估为Ⅲ、Ⅳ期放弃手术而行介入和化疗。CT表现为胃壁增厚、软组织肿块、胃壁多层结构破坏。淋巴结及邻近、远处脏器的侵犯及转移分别为40.1%、16.9%和20%。CT分期与手术病理分期相符者43例,胃癌CT分期总的准确率82.7%。结论:MSCT在进展期胃癌诊断、分期及可切除性判断等方面具较高的价值,能够为临床诊治提供有益的指导。Objective：To evaluate the value of triple-phase dynamic multi-slice spiral CT （MSCT） with water distention and induced hypotonia in the preoperative diagnosis, staging and assessment of resectability of advanced gastric carcinoma. Methods：Sixty-five patients with advanced gastric carcinoma underwent triple-phase dynamic enhanceed MSCT. Preoperative CT diagnosis, staging and assessment of resectability were made and correlated with that of operation and pathology. Results：Fifty-two patients underwent operation while the other 13 with stage Ⅲ and Ⅳ disease underwent interventional and chemical therapy. Involvement of local lymph nodes,invasion of adjacent organs and metastasis to distant organs were detected in 40.1% ,16.9% and 20% of the cases,respectively. The overall accuracy of tumor staging was 82.7% for MSCT with 43 cases were correctly staged. Conclusion： MSCT is of high value in diagnosis,staging and assessment of resectability of advanced gastric carcinoma.
