【摘要】：正随着人类对嗅觉功能认知的重视和深入研究,逐渐发展出多种嗅觉系统的检测方法。主客观嗅觉功能检查能够从不同层面反应嗅觉的水平,尤其客观检测目前被认为是评估嗅觉功能的"金标准"。但是这些检查不能确定嗅觉信号产生的部位,以及引起嗅觉障碍的原因。影像学技术则能够显示嗅觉通路结构,并且功能性MRI(functional MRI,fMRI)和正电子发射计算机断层扫描(positron emission tomography,PET)等可以反应大脑不同区域对特定刺激的功能活性。相对于CT扫描,
[Abstract]:With the attention and research of olfactory function, many detection methods of olfactory system have been developed. Subjective and objective olfactory function examination can reflect olfactory level from different levels, especially objective detection is considered to be the "golden standard" to evaluate olfactory function. However, these tests do not determine where the olfactory signals are produced and the causes of olfactory disorders. Imaging techniques can display olfactory pathway structures, and functional MRI (functional MRI,fMRI) and positron emission computed tomography (positron emission tomography,PET) can reflect the functional activity of different regions of the brain to specific stimuli. Relative to CT scanning,
