摘　　要：目的:评价 US、CT、MRI、ERCP、EUS 五种影像学检查对胰腺癌诊断的敏感性。方法:36例胰腺癌患者术前同时进行 US、CT、MRI、ERCP 和EUS 检查,均行手术与病理对照。结果:36例胰腺癌中,病灶<2cm 占22.2％,>2cm 占77.8％US、CT、MRI、ERCP 和 EUS 对胰腺癌检查总的准确率分别为72.2％、63.9％、86.1％、88.9％和100％,经统计学检验,EUS 和 US、CT 间存在显著性的差异(p<0.05);在 EUS、ERCP 和 MRI 间无明显差异(p>0.05),而 MRI 优于 CT(p<0.05)。对<2cm 癌肿检查的准确率分别为50％、25％、62.5％、75％、100％,EUS 明显高于 ERCP 和 MRI(p<0.05)。结论:EUS 对胰腺癌是一种敏感的检查方法,明显优于 US 和 CT;MRI 是对胰腺癌诊断重要的补充;ERCP 对胰腺癌的诊断是一种较好的方法,但一般不作为首选。To evaluated the diagnosis of pancreatic carcinoma by US,CT,MRI,ERCP and EUS.Methods:Five methods were performed in all 36 cases of pancreatic carcinoma in peroperation,and confirmed by surgery and pathology, the results of detection were compared analyzed.Results:The diameter of pancreatic carcinoma lesion<2cm and>2cm were 22.2% and 77.8%,respectiviely.The overall sensitivity of detecting pancreatic carcinoma with US,CT,MRI,ERCP and EUS were 72.2%,63.9%,86.1%,88.9%,and 100%,respectively.The significant difference (p<0.05) was noted between EUS with US and CT.There is no remarkable difference(p>0.05) among EUSI ERCP and MRI,but MRI is superior to CT(p<0.05).The sensitivity of revealing the lesion diameter<2cm were 50%、25%、62.5%、75% and 100%,respectively,and it is remarkable higher of EUS than ERCP or MRI.Conclusion:EUS is superior to US and CT, and it is one of the best diagnostic modalities to detect pancreatic tumors.MRI is very important supplementary method, and ERCP is a better method in the diagnosis of pancreatic carcinoma,but it is not used as a primary examination of choice.
