低张力MRI对十二指肠乳头区疾病的诊断价值

Comparison of various imaging methods in the diagnosis of diseases in the duodenal papillary region

目的:探讨低张力MRI在诊断十二指肠乳头区病变中的应用价值。方法:对临床可疑十二指肠乳头区病变患者46例进行低张力MRI及MRI胰胆管成像(MRCP)检查,分析其MRI表现并与其它影像学检查对比分析,总结其影像学特点。结果:对十二指肠腔内病变的诊断,低张力MRI检查与纤维十二指肠镜检查的检出率和特异性基本相当,优于上消化道造影和CT(P<0.01);对十二指肠腔外病变的诊断,低张力MRI检查的病变发现率及诊断率均高于其他检查方法(P<0.01)。结论:低张力MRI结合MRCP可作为十二指肠乳头区全面、精细的无创检查方法。

Objective To study the value of the hypotonic MRI in the diagnosis of diseases in the duodenal papillary region. Methods Forty six patients studied with the hypotonic MRI combined with MRCP CT endoscopy and gastrointestinal barium meal study. Their radiological characteristics were analyzed. Results The ability of MRI combined with MRCP in diseases of duodenum was similar to endoscopy superior to CT and gastrointestinal barium meal study and MRI combined with MRCP in evaluating tumor was superior to other methods. Conclusion Hypotonic MRI combined with MRCP may be taken as a non invasive and detailed method in evaluating diseases in the duodenal papillary region.
