摘要 目的:评价MRCP检查对婴儿梗阻性黄疸的诊断价值方法:临床诊断为梗阻性黄疸的患儿14例,5例非肝胆道疾病患儿作对照.所有患儿扫描序列包括快速自旋回波LOTAT1WI序列、半傅立叶采集单次激发快速自旋回波(HASTE)和2D快速自旋回波的MRCP水成像序列.在分析时照组5例婴儿正常的胆道系统MRI表现的基础上,将梗阻性黄疸患儿的MRI征象与手术、病理结果对照,重点评价MRCP诊断的敏感性和特异性. 结果:5例非肝胆道疾病MRI表现肝脏大小正常,肝门区未见异常信号,胆囊充盈4例,胆囊未见显示1例;MRCP 肝内一级胆管、肝外胆管均可见完整显示.MRI诊断的9例胆道闭锁,表现为肝脏增大,以右下叶增大为主:肝门区门静脉周围有异常信号,T1呈较低信号,T2呈较高信号6 例,1例可见肝门部的三角形T2呈高信号影;胆囊细小5例, 未见显示4例;MRCP肝内外胆管均未见显示.MRI诊断的5 例婴儿肝炎综合征,表现为肝脏增大,肝门区未见异常信号;胆囊充盈3例,胆囊细小2例;MRCP肝内一级胆管、肝外胆管均见显示5例.14例梗阻性黄疸患儿,最后手术证实胆道闭锁9例、婴儿肝炎综合征5例.术前1例胆道闭锁误诊为婴儿肝炎综合证,1例婴儿肝炎综合证误诊胆道闭锁.MRCP 对婴儿梗阻性黄疸诊断的敏感性100%,特异性85.7%. 结论:MRCP是诊断婴儿梗阻性黄疸,尤其是胆道闭锁和婴儿肝炎综合征敏感的检查方法,可为临床鉴别胆道闭锁和婴儿肝炎综合征提供依据.
