OBJECTIVE
To evaluate the value of spiral computed tomography(sCT) in the judgement of gross type, invasion to serosa and adjacent organs of advanced gastric carcinoma.
METHODS
The sCT results of 53 cases of advanced gastric carcinoma undergone gastrectomy were compared with surgical pathologic findings.
RESULTS
The accuracy of judging gross type, location and size of gastric carcinoma was 92.5%, 88.7%, 81.1% respectively; 80.5% of serosal invasion was correctly judged by extraluminal fat sign, while 63.4% by serosal contour sign (P < 0.05). Different serosal types could be differentiated by CT features. The accuracy of judging invasion to pancreas, spleen and transverse colon was 87.8%, 87.8%, and 90.2%; and the specificity was 96.7%, 97.0% and 96.7%, respectively.
CONCLUSION
Spiral computed tomography is of help in the identification of the gross type, invasion to serosa and adjacent organs of gastric cancer in its stage of progression.
目的
评估螺旋计算机断层扫描（sCT）在判断进展期胃癌大体类型、浆膜及邻近器官受侵情况中的价值。
方法
将53例行胃癌根治术的进展期胃癌患者的sCT检查结果与手术病理结果进行对比。
结果
sCT判断胃癌大体类型、部位及大小的准确率分别为92.5%、88.7%、81.1%；通过腔外脂肪征判断浆膜受侵的准确率为80.5%，通过浆膜面轮廓征判断的准确率为63.4%（P<0.05）。不同浆膜类型可通过CT特征进行鉴别。判断胰腺、脾脏及横结肠受侵的准确率分别为87.8%、87.8%、90.2%；特异性分别为96.7%、97.0%、96.7%。
结论
螺旋计算机断层扫描有助于判断进展期胃癌的大体类型、浆膜及邻近器官受侵情况。
