摘要
描述胃癌的ＣＴ表现，评价胃癌术前ＣＴ分期的准确性，以总结ＣＴ在胃癌诊断中的应用价值。材料和方法：口服水对比剂充盈胃增强ＣＴ扫描，检查已知胃癌病者５５例，并将ＣＴ发现与手术病理进行对照。结果：胃癌灶在ＣＴ上表现为胃壁增厚（３８／５５），软组织肿块（１７／５５）及异常强化（４８／５５）。本组ＣＴ术前分期总的准确性为８１．８％，胃癌可切除性术前估价准确性为８９％。结论：ＣＴ检查在胃癌的检出及术前分期等方面具有较大的实用价值。
Purpose: To delineate the CT appearance of gastric carcinoma, evaluate the accuracy of CT in preoperative gastric carcinoma staging and find the rold of CT in the diagnosis of gastric carcinoma. Materials and Methods: 55 cases of known gastric carcinma were prospectively studied by means of enhanced CT performed with water-filling method. The CT findings were compared with the surgical pathology. Results: CT demonstrated gastric tumor as a thickened gastric wall in 38 of 55 cases,soft tissue mass in l7 cases and abnormally enhanced in 48 cases. 45 of 55 patients(81.8%) were correctly staged with CT. The accuracy of preoperative evaluation of tumor resectability by CT was 89%.Concltision:CT examination is of value in the diagnosis and staging of gastric carcinoma.
