経頭蓋MRガイド下集束超音波治療（transcranial MR-guided focused ultrasound surgery：TcMRgFUS）へのfiber tractography解析の応用

Abstract

Transcranial MR-guided focused ultrasound surgery (TcMRgFUS) is recognized as a minimally invasive treatment method for essential tremor (ET), a condition characterized by involuntary motor disturbances. The target region for treating ET is the ventral intermediate (Vim) nucleus of the thalamus, which is surrounded by the ventral caudal nuclei (Vc) and the pyramidal tract (PT).
