目的：探讨磁化传递（MT）技术与时间飞跃法（3D-TOF）在磁共振血管成像（MRA）中的应用价值比较。方法对82例患者同时行磁化传递（MT）技术法和常规3D-TOF 法的MRA 扫描，并对两者原始图像进行三维重组、对比分析。结果磁化传递（MT）技术法MRA 的血管背景被完全抑制，分支小血管显示清晰，而常规3D-TOF 法MRA 的血管背景抑制不全，末梢分支小血管显示不清或未显示。结论磁化传递（MT）技术法较常规3D-TOF 法的MRA 更能获得高清晰血管图像。

Objective To compare the application value between MT technology and 3D-TOF in MRA. Methods Eighty-two patients accepted MRA scanning by both MT technique and conventional 3D-TOF method ,the original images of the both kinds were done with three-dimensional reconstruction and analyzed.Results MT MRA vascular background was completely inhibited ,branches of small vessels were clearly displayed ,and the vascular background suppression of conventional 3D-TOF MRA was not complete ,peripheral branches of small vessels were not clear or not shown.Conclusion The MT method is su-perior to the conventional 3D-TOF method MRA to obtain high clear vascular images.
