目的 :探讨术前应用磁共振成像 (MRI)对胃癌原发灶的诊断价值。方法 :采用单次屏气快速MRI扫描序列 ,对 2 0例进展期胃癌患者进行扫描 ,根据手术、病理、胃镜结果对MRI表现进行分析。结果 :进展期胃癌检出率达 10 0 % ,胃癌在T1WI上呈等信号或稍低信号 ,T2 WI上呈低信号。结论 :进展期胃癌在MRI上的表现具有特征性。MRI是一项有价值的胃癌检查方法。
Objective: To investigate the value of preoperative application of magnetic resonance imaging (MRI) in the diagnosis of primary gastric cancer. Methods: Twenty patients with advanced gastric cancer underwent a single breath-hold rapid MRI scanning sequence. The MRI findings were analyzed according to the results of surgery, pathology and gastroscopy. Results: The detection rate of advanced gastric cancer was 100%. The gastric cancer showed equal signal or slightly lower signal on T1WI and low signal on T2WI. Conclusions: The performance of advanced gastric cancer on MRI is characteristic. MRI is a valuable method of gastric cancer examination.
