摘　　要：目的比较计算机断层扫描(CT)检查与磁共振成像(MRI)检查对胰腺囊腺癌的诊断价值。方法回顾性分析160例疑似胰腺囊腺癌患者的临床资料,患者均进行CT检查与MRI检查,以病理检查结果为"金标准",比较2种检查方法对胰腺囊腺癌的诊断价值,并记录检查时间。结果 160例疑似胰腺囊腺癌患者中,病理检查确诊胰腺囊腺癌50例,良性肿瘤110例。CT检出胰腺囊腺癌45例,MRI检出胰腺囊腺癌48例;MRI检查的准确度、特异度、灵敏度、阴性预测值及阳性预测值均略高于CT检查,但差异无统计学意义(P> 0.05);胰腺囊腺癌在CT上均表现为囊性低密度影,囊内见结节或线样分隔,囊壁清,部分囊内见实性成分;胰腺囊腺癌T1WI表现为低至中等信号,T2WI表现为等至高信号,囊壁结节及实性部分信号与软组织信号相似,增强扫描囊壁和实性部分呈中度至明显强化。结论 CT检查与MRI检查各有优势,在胰腺囊腺癌的诊断中均具有较高的应用价值,均能够充分表现病灶影像学特征,为胰腺囊腺癌的临床诊断提供参考依据。Objective To compare the value of computed tomography (CT) scan and magnetic resonance imaging (MRI) in the diagnosis of pancreatic cystadenocarcinoma. Methods The clinical data of 160 patients with suspected pancreatic cystadenocarcinoma was retrospectively analyzed and they all underwent CT and MRI examinations. Using the pathological examination result as the "gold standard",the value of the two examination methods in diagnosing pancreatic cystadenocarcinoma was compared,and the examination time was recorded. Results Among 160 patients with suspected pancreatic cystadenocarcinoma,a total of 50 patients were diagnosed as pancreatic cystadenocarcinoma after pathological examination,the remaining 110 cases were benign tumors. Pancreatic cystadenocarcinoma was detected in 45 cases by CT,and in 48 cases by MRI. The accuracy,specificity,sensitivity,negative predictive value and positive predictive value of MRI examination were slightly higher than those by CT examination,but the difference showed no significant difference (P > 0. 05).CT findings of pancreatic cystadenocarcinoma showed that low-density cystic masses,nodules or linear divisions in the capsule were seen,and the capsule wall was clear,substantial tissue could be seen in some capsules of patients. MRI findings showed that patients presented low to medium signals on T1 weighted image,and equal or high signals on T2 weighted image. The signals of capsule wall nodule and solid part of cyst were similar to that of soft tissue,and the enhanced scan of the cyst wall and the solid part showed moderate to obvious enhancement. Conclusion Both CT and MRI are of high value in the diagnosis of pancreatic cystadenocarcinoma,and each has its own advantages. In addition,the imaging features of the lesion can be fully displayed,which can provide a reference for clinical diagnosis.
