摘　　要：目的　分析ＭＲＩ在胃癌诊断和术前分期中的应用价值。方法　对３２ 例经病理证实为胃癌的患者行ＭＲＩ多方位（ 冠状、矢状、轴位）扫描，分析其ＭＲＩ表现并进行分期。结果　ＭＲＩ能清楚显示进展期胃癌的准确部位、实际范围、大小、外侵程度及其与邻近结构的关系。ＭＲＴ分期与病理分期对照，对Ｔ２ ，Ｔ３ ，Ｔ４ 期胃癌的诊断准确率分别为７７－８ ％ ，８２－１％ ，１００％ ，总准确率为８４－４％ ，注射Ｇｄ－ ＤＴＰＡ 增强扫描，大多数胃癌呈中强度增强，少数呈轻度增强。结论　①ＭＲＩ能明确提示进展期胃癌的诊断，具有重要临床意义。②胃癌的ＭＲＩ分期能为手术方案的制定提供依据。Purpose To analyze the value of MRI in gastric carcinoma diagnosis and predicting presurgical.Methods scanning 32 cases proved Gastric carcinoma by pathology with MRI (coronal,sagital,axial),analysing MR imaging and staging. Results MRI clearly demonstrated the location,actual lengh, and extent of gastric carcinoma as well as its relation with surrounding structures in all cases contrasting. MRI staging pathology, the accuracy of T 2,T 3,T 4 was 77.8%, 82.1%, 100%, the overall accuracy was 84.4%. Enhannced MRI scan, gastric carcinoma marked heterogeneous enhancement. A few were little enhancement. Conclusion ①MRI scaning plays a significant role in the diagnosis of gastric carcinoma. ②MRI staging of gastric carcinoma can prove basis for surgical. [
