摘　　要：目的比较原发性胰腺癌应用CT和MRI增强扫描的效果。方法整群选取并回顾性分析该院于2012年2月—2015年2月期间,治疗的33例原发性胰腺癌患者临床资料,对所有患者均进行应用CT和MRI增强扫描检查,对病理检查结果对比,对比CT和MRI增强扫描对原发性胰腺癌的诊断准确率,对不同大小肿块的检出率及误差率。结果在33例原发性胰腺癌患者中,CT增强扫描的诊断准确率为69.70%,MRI增强扫描的诊断准确率为87.88%;MRI增强扫描对原发性胰腺癌的诊断准确率显著大于CT增强扫描,差异有统计学意义(P<0.05);33例原发性胰腺癌患者共发现38个病灶,手术病理证实直径>1 cm的病灶35个,<1 cm的病灶3个;CT检查显示直径>1 cm的病灶33个,<1 cm的病灶5个,检出率为86.84%,误差率为13.16%;MRI增强扫描显示直径>1 cm的病灶36个,<1 cm的病灶2个,检出率为94.74%,误差率为5.26%;两组数据差异无统计学意义(P>0.05)。结论 CT和MRI增强扫描诊断原发性胰腺癌的临床效果确切,均作为临床准确检查诊断原发性胰腺癌的有效影像学方法,对微小病灶的检出率较高,误差率较低,但MRI增强扫描对原发性胰腺癌的诊断准确率大于CT增强扫描,更具有临床可行性。Objective To compare the effect of CT and MRI enhancement scanning in the application of primary pancreatic carcinoma. Methods The clinical data of 33 cases with primary pancreatic carcinoma treated in our hospital from February2012 to February 2015 were retrospectively analyzed and all patients were examined by CT and MRI enhancement scanning, the pathological examination results were compared, the diagnostic accuracy rate of CT and MRI enhancement scanning for primary pancreatic carcinoma, detection rate of tumor in different sizes and error rate were compared. Results The diagnostic accuracy rate of CT and MRI enhancement scanning, for the 33 cases of patients with primary pancreatic carcinoma, was respectively 69.70% and 87.88%, the diagnostic accuracy rate of MRI enhancement scanning for primary pancreatic carcinoma was obviously higher than that of CT enhancement scanning, there was an obvious difference（P〈0.05）, 38 lesions were discovered in 33 cases of patients with primary pancreatic carcinoma, there were 35 lesions whose diameter was more than 1cm and 3 lesions whose diameter was less than 1cm confirmed by pathology and surgery, there were 33 lesions whose diameter was more than 1cm and 5 lesions whose diameter was less than 1cm revealed by CT examination, the detection rate was 86.84% and the error rate was 13.16%, there were 36 lesions whose diameter was more than 1 cm and 2lesions whose diameter was less than 1cm revealed by MRI enhancement scanning, the detection rate was 94.74% and the error rate was 5.26%, there was no obvious difference between the two data（P〉0.05）. Conclusion CT and MRI enhancement scanning in diagnosis of primary pancreatic carcinoma have a definite clinical effect, and it can be used as an effective imaging method of the accurate examination and diagnosis of primary pancreatic carcinoma in clinic with higher detection rate of micro-lesions and lower error rate, but the diagnostic accuracy rate of MRI enhancement scanning for primary pancreatic carcinoma is higher t
