| 目的 探讨3D-VIBE序列增强扫描在面神经炎患者磁共振检查中的技术应用价值。方法 对32例经临床确诊为面神经炎的患者，采用3T超导型磁共振成像仪（Verio SIEMENS）的3D-VIBE序列进行磁共振增强检查，分别测量增强前、后患侧和健侧面神经迷路段、鼓室段和乳突段的信号强度S，根据所得数据计算出面神经强化率，判断面神经的强化程度。结果 32例患者的面神经迷路段、鼓室段和乳突段全部显示清晰，并能显示出面神经和血管之间的关系，均达到临床诊断标准。根据所得数据计算出患侧面神经迷路段、鼓室段和乳突段的ΔS%值（S值变化率）均高于健侧，经非参数检验，差异具有统计学意义（P<0.05）。结论 3D-VIBE序列增强扫描对诊断面神经炎有重要作用。 |

| Purpose Explore the using value of enhanced 3D-VIBE sequence of MRI scan in patients with facial paralysis technology. Materials and Methods We let 32 patients with clinically diagnosed facial paralysis do MRI examination by 3D-VIBE sequence of 3T superconducting magnetic resonance scanner (Verio SIEMENS).We measured the signal intensity Soflabyrinthine segment, tympanic segment and mastoid segment of the ipsilateral and healthy sideoffacial nerve before and after enhancement, then we calculated the enhancing ratio based on the data to determine the strengtheningextent of the facial nerve.Results The labyrinthine segment, the tympanic segment and mastoid segment of the facial nerve of 32 cases display all clear, and can show the relationship between the nerves and blood vessels and are able to meet the clinical diagnostic criteria.According to the data ,we calculate ΔS(the variance ratio of S )of the labyrinthine segment,the mastoid segment and the tympanic segment of facial nerve, the ipsilateral side were higher than the healthy side, the difference was statistically significant (p <0.05).Conclusion 3D-VIBE sequence of the enhanced MRI scan on an important role in the diagnosis of facial paralysis. |
