摘　　要：目的评价Ｆａｓｔ—ＡＳＥ序列胆胰管成像技术的临床意义。材料和方法共检查病人１１５例，其中梗阻黄疸者７０例，应用２Ｄ、３ＤＦａｓｔ—ＡＳＥ序列，屏气，重Ｔ_２ＷＩ成像技术，３Ｄ原始图像经工作站处理后，得到“三维立体”的造影图像。结果　全部检查均获成功，可清楚显示胆道、胆囊和胰管，对管腔狭窄、梗阻、扩张和充盈缺损的发现准确性高。结论Ｆａｓｔ－ＡＳＥ是在ＦＳＥ基础上开发的先进扫描技术，克服了传统ＦＳＥ序列的缺点，可在较短时间内获得高质量的胆胰管成像。Purpose To assess the clinical role of Fast--ASE squence in magnetic resonance cholangiopancreatography (MRCP)technique. Materials and method 115 cases with 70 cases of obstructive jaundice by MRCP technique with a breath -- hold heavily T2 -- weighted 2D, 3D-- Fast -- ASE sepuence. The original images were postprocessed on 3D workstation in some cases. Results MRCP technique with Fast --ASE sequence was succesful in all patients,which can demonstrate narrowing,dilatation and filling defect of ducts fairly well. Conclusion Fast --ASE is the advanced scanning technique now that is based on FSE,which offers advantages compared with FSE techniques. Using Fast--ASE,the MRCP with high image quality can by performed in a short time.
