摘　　要：目的　评价术前应用磁共振成像 (MRI)对胃癌原发灶及转移灶的诊断价值。方法　应用超导型磁共振成像仪单次屏气快速扫描序列对 36例胃癌患者进行术前检查 ,并经手术及病理学检查证实。结果　MRI对胃癌病灶的定性定位诊断率达 10 0 % ,淋巴结转移显示率为 83% (2 5 / 30 ) ,腹部脏器转移或侵犯诊断正确率为 73% (35 / 48)。结论　胃癌在MRI上有特征性表现 ,该方法能较好地显示胃癌及其扩散 ,甚至转移淋巴结情况 ,对进展期胃癌的临床诊断有较高的应用价值。Objective To evaluate the diagnostic value of preoperative MRI for advanced gastric cancer and metastasis. Methods MRI was preoperatively performed in 36 patients with advanced gastric carcinoma by the superconductive type of magnetic resonance imaging instrument through a single breath holding fast scan sequence, the results were correlated with the intraoperative and histopathologic findings.[WT5”HZ] Results[WT5”BZ] The correct rate of localization and qualitative determination in gastric carcinoma by MRI were both 100%. The displaying rate of metastatic lymph notes was 83%(25/30), and the correct diagnostic rate was 73%(35/48) for metastasis or invasion to adjacent abdominal organs.[WT5”HZ] Conclusions[WT5”BZ] Gastric carcinoma shows characteristic MRI pictures, hence MRI examination has the advantage of diagnosing gastric cacinoma, its spreading, even metastasis of lymph nodes.
