摘要
目的:研究胃癌的MRI表现和诊断价值。材料与方法:采用单次屏气快速MR扫描序列,对30例胃癌患者进行扫描,根据手术、病理、胃镜、钡餐结果对MRI表现进行回顾分析。结果:MRI顺利显示了胃癌的部位、形态。胃癌在T1WI和T2WI上均呈低信号。10/12(83%)例有明显强化。12/30(40%)例患者邻近胃癌的胃壁出现了分层现象。本组病例共有43个腹部脏器受累,MRI显示了31个(72%)。淋巴结转移21例,MRI显示了18例(86%)。结论:MRI能较好显示胃癌及其扩散情况,是一项有价值的检查方法。
Objective: To study the MRI features of gastric carcinoma and their diagnostic value. Materials and Methods: MRI using single breathholding fast scan sequence was performed in 30 patients with gastric carcinoma. Compared with surgery, pathology, gastroscopy and barium meal examination, the MRI findings were analyzed retrospectively. Results: The site and shape of the tumors were well demonstrated on MRI. On both T1WI and T2WI, all the tumors showed hypointensive signal. Remarkable enhancement was seen in 10/12 (83%) cases. The gastric wall near the lesion manifested layered phenomenon in 12/30 (40%) patients. MRI revealed 72% (31/43) abdominal organ invasion and 86% (18/21) lymph node metastasis. Conclusion: MRI is very helpful in demonstrating the gastric tumor and its spreading extent.
