CT、MRI对胰腺囊性病变的鉴别诊断价值分析

Differential Diagnosis Value of CT and MRI for Pancreatic Cystic Lesions

目的分析CT、MRI对胰腺囊性病变的鉴别诊断价值。方法回顾性分析本院2016年4月至2018年11月收治的70例胰腺囊性病变患者的临床资料,分析胰腺囊性病变的影像学表现;以病理检查结果为“金标准”,比较CT和MRI检查胰腺囊性病变的诊断准确率及CT与MRI检查所用时间。结果70例胰腺囊性病变患者经CT检查诊断出66例,诊断准确率为94.29%;MRI检查诊断出68例,诊断准确率为97.14%;CT、MRI检查结果与病理检查结果比较差异无统计学意义(P>0.05),其中MRI检查结果与CT比较差异也无统计学意义(P>0.05),CT检查胰腺囊性病变时间明显短于MRI检查(P<0.05)。结论MRI和CT检查均可有效显示胰腺囊性病变的影像学特点,均具有较高的诊断准确率,临床可结合患者实际情况,选择最佳的诊断方法。

Objective To analyze the differential diagnosis value of CT and MRI for pancreatic cystic lesions.Methods The clinical data of 70 patients with pancreatic cystic lesions admitted to our hospital from April 2016 to November 2018 were analyzed retrospectively.The imaging features of pancreatic cystic lesions were analyzed.The results of pathological examination were“gold standard”to compare the diagnostic accuracy of CT and MRI for pancreatic cystic lesions and to compare the time used for CT and MRI examinations.Results 60 patients with pancreatic cystic lesions were diagnosed by CT examination,and the diagnostic accuracy was 94.29%.68 patients were diagnosed by MRI,and the diagnostic accuracy was 97.14%.There was no statistical difference between results of CT and MRI and results of pathological examination.There was no significant difference between the results of MRI and CT(P>0.05).The time of CT examination for pancreatic cystic lesions was significantly less than that of MRI(P<0.05).Conclusion Both MRI and CT examinations can effectively display the imaging features of pancreatic cystic lesions,and they all have high diagnostic accuracy.In clinic,the best diagnostic method can be selected based on the actual situation of the patient.
