摘　　要：目的评估2D-MR胰胆管造影(MRCP)和平衡梯度回波(BFFE)序列联合应用对老年胆总管结石的诊断价值。材料与方法搜集2010年1月至2011年12月间进行MRCP检查≥70岁的114例怀疑胆总管结石的患者资料。由2名医师观察2D-MRCP图像,结合BFFE、T2WI评价是否存在胆总管结石。结果所有病例中MRCP能清晰显示胆道系统,114例患者中MR图像提示108例患者合并胆总管结石,6例患者无胆总管结石;手术及ERCP结果显示99例患者合并胆总管结石,15例患者无胆总管结石;对两组结果进行卡方检验差异有统计学意义(χ2=4.281,P=0.031)。结论 2D-MRCP结合BFFE序列能准确获得老年患者胆总管是否存在结石的情况,具有快速、安全的特点,特别适合不合作的患者。Objective： The purpose of our study was to assess the clinical usefulness of conventional two-dimensional（2D） magnetic resonance cholangiopancreatographic（MRCP） and balance fast field echo（BFFE） sequence in older patients with common bile duct stones（CBDS）.Materials and Methods： MRCP preformed in 114 older patients,who with sepected CBDS,ranged from 2010-1 to 20011-12,two reviewers was present retrospectively evaluated MRCP images with 2D-MRCP,BFFE and T2weighted MR images.The results compared with ERCP or surgical findings.Results： CBDS was found in 108 of 114 patients with MRI.CBDS was found in 99 of 114 patients with ERCP or surgical findings.The correlation of MRI and ERCP or surgical findings was calculated（χ2=4.281,P=0.031）.Conclusions： 2D-MRCP with BFFE is a safe,effective means of mamaging sepected common bile duct stones of older noncooperative patients.
