核磁共振能检查胰腺癌 胰腺癌MRI检查的最佳扫描序列及MRI表现分析

2019-10-21 20:02:10 分类:内科
检验比较各序列对病灶检出的敏感性和特异性。结果 mri对胰腺癌的总的诊断准确率为91.9%(57/62);dcefmpspgr序列对病灶检出率为95%(57/60);se t 1 wi、se t 2 wi和se t 1 wi+fs对病灶的检出率分别为70.9%(44/62)、83.9%(52/62)、89.9%(32/36)。其中dcefmpspgr和se t 1 wi+fs之间无统计学差异(p>0.05),但均同set 1 wi有差异(p1 wi+fs为最佳,可以较好地反映胰腺癌的病理特征。

【abstract】 objective to discuss mri appearances of pancreatic carcinoma on conventional se sequences and dynamic contrast-enhanced gradient echo sequence,and meanwhile comparing and analyzing the sensitivity and specificity of several sequences in detection of pancreatic carcinoma retrospectively,which are applied in routine cliniˉcal practice.methods sixty-five cases of pancreatic carcinoma proved by surgico-pathology were studied,mri seˉquences such as se t 1 wi,t 2 wi and dynamic contrast enhanced gre triphase scans were performed to60cases,aˉmong of them,36cases were additionally investigated by se t 1 wi+fs scans;in the remaining5cases,3cases were only for coronal mra scans and2cases were for se t 1 wi and t 2 wi scans.results overall diagnostic accuracy of mr imaging for pancreatic carcinoma was91.9%(57/62).the detection rate of pancreatic carcinoma was95%(57/60)for dcefmpspgr,70.9%(44/62)for se t 1 wi,83.9%(52/62)for se t 2 wi,89.9%(32/36)for se t 1 wi+fs respectively,hepatic metastases detection rate were accounted for40%(26/65).the peripancreatic vessels’invaˉsion by tumors were as following:superior mesenteric vein in44cases,superior mesenteric artery in42cases,celiac trunk in22cases,portal vein in19cases,splenic vein in19cases,splenic artery in18cases,common hepatic artery in8cases,inferior vena cava in7cases,aortic artery in2cases,left kidney vein in1case,middle colic artery in1case,collateral vessels were found in5cases,lymph metastases in14cases,ascites in6cases and thorax liquid in1case.conclusion mr imaging especially for fmpspgr and t 1 wi+fs sequences have fairly high diagnostic accuracy inpancreatic carcinoma,and could demonstrate pathological features of pancreaticcarcinoma as well.
