目的比较磁共振成像(MRI)和经内镜逆行性胰胆管造影术(ERCP)在壶腹区病变诊断中的应用价值。方法 70例壶腹区病变患者随机分为研究组(40例)和对照组(30例)。研究组采取磁共振成像方法进行诊断,对照组采取经内镜逆行性胰胆管造影术进行诊断,分析诊断的准确性。结果研究组的诊断准确率为92.5%(37/40)高于对照组的诊断准确率73.3%(22/30),组间比较差异有统计学意义(P>0.05)。结论 MRI特别是3D-CE-LAVA和3DMRCP,可以对壶腹区病变的位置、程度、范围以及性质给予清晰的显示,属于壶腹区病变诊断的首选方法 ,值得临床推广使用。
Objective To compare the value of magnetic resonance imaging (MRI) and endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis of ampullary lesions. Methods 70 cases of ampulla lesions were randomly divided into study group (40 cases) and control group (30 cases). The study group to take the magnetic resonance imaging method for diagnosis, the control group to adopt endoscopic retrograde cholangiopancreatography diagnosis, analysis of diagnostic accuracy. Results The diagnostic accuracy of the study group was 92.5% (37/40), which was significantly higher than that of the control group (73.3%, 22/30). There was significant difference between the two groups (P> 0.05). Conclusions MRI, especially 3D-CE-LAVA and 3DMRCP, can clearly show the location, extent, range and nature of lesions in the ampulla, which is the preferred method for diagnosis of ampulla lesions and is worthy of clinical promotion.
