Abstract

The role for neuroimaging in the management of patients with tremor is gradually increasing, particularly with respect to stereotactic neurosurgery and deep brain stimulation where less than 2-mm tolerance is required for accurate electrode placement. The routine use of single photon emission CT technology to image the nigrostriatal dopaminergic system is proving helpful in distinguishing essential and dystonic tremors from neurodegenerative forms of parkinsonism and in improving our understanding of the pathophysiology of rarer tremors.

摘要

神经影像学在震颤患者管理中的作用逐渐增加，特别是在立体定向神经外科和深部脑刺激方面，需要小于 2 毫米的容差才能实现准确的电极放置。单光子发射 CT 技术常规用于成像黑质纹状体多巴胺能系统，有助于区分特发性震颤和肌张力障碍性震颤与神经退行性帕金森病，并有助于更好地了解罕见震颤的病理生理学。
