摘要:目的探讨单次屏气磁共振胰胆管成像(MR cholangiopancreatography,MRCP)与平衡驱动快速梯度回波技术(balanced fast field echo,B-FFE)相结合在胆系结石诊断中的应用价值.方法分析手术证实的100例胆系结石患者,经过用常规轴位T2W/TSE、T2W/SPIR、T1W/FFE、DYNAMIC/T1W增强扫描及SSH-RADIAL MRCP、B-FFE扫描所得图像.结果 1.MRCP显示肝内胆管结石8例,肝外胆管结石68例,胆囊结石59例.2.B-FFE显示肝内胆管结石9例,肝外胆管结石64例,胆囊结石63例.结论 1.单次屏气MRCP是一种显示胆胰管的优秀MR成像技术.2.B-FFE通过断层的方法进一步了解胆管内外解剖结构.3.两者相结合可提高胆系结石的显示率.
