BACKGROUND/AIMS: We evaluated the usefulness of CT gastrography in preoperative localization of gastric cancer.
METHODOLOGY
CT gastrographic images of 213 patients with gastric cancer were evaluated for localization of tumor. For the precise localization we developed a software module to measure the shortest distances from tumor to the esophagogastric junction and to the pylorus on the images. After gastrectomy, these were compared with the shortest distances on surgical specimen.
RESULTS
The localization rates of advanced and early gastric cancer were 100.0% and 88.8%, respectively. There were significantly linear relationship between the shortest distances measured on CT gastrographic images and those on surgical specimen.
CONCLUSION
CT gastrography could be a useful preoperative localization tool.
背景/目的：我们评估了CT胃造影术在胃癌术前定位中的作用。
方法
对213例胃癌患者的CT胃造影图像进行肿瘤定位评估。为了精确定位，我们开发了一个软件模块来测量图像上肿瘤到食管胃交界处和幽门的最短距离。胃切除术后，将这些距离与手术标本上的最短距离进行比较。
结果
进展期和早期胃癌的定位率分别为100.0%和88.8%。CT胃造影图像上测量的最短距离与手术标本上的最短距离之间存在显著的线性关系。
结论
CT胃造影术可能是一种有用的术前定位工具。
