目的：探讨磁化传递技术在颅脑MRA检查中的应用价值。方法对58例脑梗死患者先后采用常规三维时间飞跃MRA（3D- TOF- MRA）（常规法）与施加磁化传递技术的3D- TOF- MRA（磁化传递法）检测颅内血管，对比分析两种图像的质量和用于诊断的价值。结果常规法血管背景组织抑制不全，对于脑血管的末梢小血管显示不清；磁化传递法MRA血管背景组织抑制充分，远端小血管显示清晰。结论使用磁化传递技术能够获得高质量的3D- TOF- MRA图像，有助于对脑血管病的诊治。

Objective To evaluate the application of magnetization transfer (MT) technology in cerebral vascular imaging with magnetic resonance angiography (MRA). Methods Fifty- eight patients underwent MRA scanning for cerebral vascular imaging from 2013 January to 2014 May with MT technique and conventional 3D- TOF method , the results of two techniques were compared. Results 3D- TOF MRA did not inhibit vascular background completely; peripheral branches of smal vessels were not clear or not shown. MT MRA was able to inhibit vascular background completely; peripheral branches of smal vessels were clearly displayed. Conclusion High quality 3D- TOF brain vascular images can be obtained with MT technique.
