摘    要:目的:探讨外伤后嗅觉功能障碍患者的嗅球MRI影像表现,分析患者嗅球体积与嗅觉功能的相关性。方法:24例头部外伤患者及25例年龄匹配健康自愿者均行嗅觉功能测试(Sniffin'Sticks)及3D-MRI扫描,分析嗅球、嗅束及嗅觉相关大脑皮层MR表现及嗅球体积。结果:24例外伤后嗅觉功能障碍患者中,10例枕部受伤并额叶眶直回挫裂伤(10/24);鼻区受伤并嗅球不同程度损伤8例(8/24);额部受伤并额叶损伤4例(4/24);2例颅底骨折并嗅球损伤(2/24)。外伤后嗅觉功能异常患者的嗅球体积小于健康志愿者即对照组(P〈0.05)。结论:MRI可以清楚显示损伤部位、范围及程度;外伤后嗅觉功能异常的嗅球体积小于对照组;证实了嗅球体积与嗅觉功能具有相关性。

关 键 词:嗅球  磁共振成像  嗅觉障碍

Abstract:Objective: To investigate the MRI manifestation of posttraumatic olfactory deficits and to analyze the changes of olfactory bulb volume in relation to olfactory function.Methods:24 patients with traumatic head injury and 25 age-matched healthy adults were tested by means of olfactory function testing using the 'Sniffin Sticks' and 3D MR imaging.MRI evaluation included extent and sites of head injury(olfactory bulbs,olfactory tracts and olfactory cortex) and changes in olfactory bulb volume.Results:Of the 24...
Keywords:Olfactory bulb  Magnetic resonance imaging  Olfaction disorders
