目的：研究ＣＴ对胃癌的诊断作用。材料方法：经病理证实胃癌７８例，其中贲门癌４３例，胃体癌１８例，胃窦癌１７例。使用美国ＧＥ公司Ｐｒｏｓｐｅｅｄ５～１０ｍｍ层厚常规扫描。结果：发现胃壁增厚３０例，肿块４６例，壁外受侵３１例，肝及肾上腺转移１９例，淋巴结转移３５例，胃壁增厚者多为浸润型，肿块多为蕈伞型和混合型。ＣＴ密度与组织学分类有关。结论：ＣＴ对中、晚期胃癌的诊断有重要帮助，尤其是对壁外侵犯和远处转移有重要作用。
Objective: To study the diagnostic role of CT in gastric cancer. Materials and Methods: 78 cases of gastric cancer were confirmed by pathology, including 43 cases of cardiac cancer, 18 cases of gastric body cancer, and 17 cases of gastric antrum cancer. U.S. GE’s Prospeed 5~10mm thickness conventional scan. Results: It was found that there were 30 cases of gastric wall thickening, 46 cases of masses, 31 cases of extravasation, 19 cases of metastasis of liver and adrenal glands, 35 cases of lymph node metastasis, and most of gastric wall thickening were infiltrative types. The masses were mostly parachute type and mixed type. . CT density is related to histological classification. Conclusion: CT has important help in the diagnosis of advanced gastric cancer, especially for extramural invasion and distant metastasis.
