| 中文摘要: |
| 偏侧面肌痉挛微血管减压术的术前评价曾应用磁共振完成,但是用二维成像评价有一定的局限性。应用融合成像三维磁共振脑池造影及复合三维磁共振血管造影术,以磁共振图像重建,获得了三维快速自旋回波序列磁共振血管造影以及三维时间飞跃扰相反转梯度回波序列脑池造影,对偏侧面肌痉挛患者压迫责任血管进行术前评价。融合成像三维磁共振脑池造影/血管造影,能为偏侧面肌痉挛患者微血管减压术外科手术提供有用的信息。 |
| 英文摘要: |
| The preoperative assessment of microvascular decompression for hemifacial spasm has been performed with MRI, but assessment of the compressive status by 20 imaging has a number of limitations. Use a fusion image of the three dimensional (3D) MR cisternograms and 3DMR angiogram, reconstructed from MR cisternogram, obtained 3D fast spin-echo sequence, and MR angiography, 3D time-of-flight and spoiled-gradient recalled sequences for the preoperative assessment of the offending artery in patient with hemifacial spasm. The fusion imaging of the 3D MR cisternogram/angiogram may provide useful information in the surgical planning of MVD for hemifacial spasm. |
