摘　　要：目的比较螺旋CT和磁共振成像(MRI)对原发性胃癌病灶诊断价值。方法入选滨州市中心医院普外科2011年1月至2013年1月收治的符合原发性胃癌诊断的66例患者,均采用螺旋CT和MRI检查,对病灶的检出情况进行对比分析。结果 MRI法胃内病灶阳性率和胃外病灶阳性率均显著高于CT组[95.5%(63/66)比84.8%(56/66),69.7%(46/66)比51.5%(34/66),P<0.05];MRI诊断胃内病灶、胃外病灶、总病灶平均个数显著高于螺旋CT[(2.7±0.3)个比(2.0±0.4)个,(2.5±0.4)个比(1.3±0.5)个,(5.0±0.4)个比(3.3±0.5)个,P<0.01]。结论 MRI检测对原发性胃癌病灶的诊断优于螺旋CT。Objective To compare the value of spiral CT and magnetic resonance imaging（MRI） in the diagnosis of primary gastric cancer.Methods A total of 66 patients with primary gastric cancer admitted in Department of General Surgery of Binzhou Central Hospital from Jan.2011 to Jan.2013 were given both spi-ral CT and MRI examinations, and the detection rates of the lesions by the two methods were compared . Results Positive rates of gastric lesions and lesions outside the stomach detected by MRI were significantly higher than those detected by spiral CT[95.5%（63/66） vs 84.8%（56/66）,69.7%（46/66） vs 51.5%（34/66）,P〈0.05];average number of gastric lesions,lesions outside the stomach and total lesions detected by MRI were significantly higher than those detected by spiral CT[（2.7 ±0.3） vs （2.0 ±0.4）,（2.5 ± 0.4） vs （1.3 ±0.5）,（5.0 ±0.4） vs（3.3 ±0.5）,P〈0.01].Conclusion MRI is superior to spiral CT detection in the diagnosis of primary gastric cancer.
