Magnetic resonance-guided focused ultrasound thalamotomy for essential tremor patients with low skull density ratio: a case-matched analysis [PDF]

Frontiers in Neurology
IntroductionSkull density ratio (SDR) is the ratio between the mean Hounsfield units of marrow and cortical bone, impacting energy transmission through the skull.

MR-guided focused ultrasound thalamotomy for lithium-induced tremor: a case report and literature review

Frontiers in Neurology
Drug-induced tremor is a common side effect of lithium with an occurrence of approximately 25% of patients. Cessation of the offending drug can be difficult, and many medical treatments for drug-induced tremor are ineffective. Deep brain stimulation (DBS)

The evolution of ventral intermediate nucleus targeting in MRI-guided focused ultrasound thalamotomy for essential tremor: an international multi-center evaluation

Frontiers in Neurology
BackgroundThe ventral intermediate nucleus (VIM) is the premiere target in magnetic resonance-guided focused ultrasound (MRgFUS) thalamotomy for tremor; however, there is no consensus on the optimal coordinates for ablation.

Neuropathology of Parkinson’s disease after focused ultrasound thalamotomy

npj Parkinson's Disease, 2022
Focused ultrasound (FUS) thalamotomy is an emerging treatment for tremor-dominant Parkinson’s disease (PD). We report the first postmortem neuropathologic study of FUS thalamotomy in a 68-year-old man with tremor-dominant PD, which was performed seven ...

Graph Theoretical Analysis of Structural Covariance Reveals the Relevance of Visuospatial and Attentional Areas in Essential Tremor Recovery After Stereotactic Radiosurgical Thalamotomy

Frontiers in Aging Neuroscience, 2022
Essential tremor (ET) is the most common movement disorder. Its pathophysiology is only partially understood. Here, we leveraged graph theoretical analysis on structural covariance patterns quantified from morphometric estimates for cortical thickness ...

Hemi-parkinsonism and return of essential tremors after MRgFUS thalamotomy: Case report and review of procedural complications affecting ventral thalamic nuclei

eNeurologicalSci, 2021
Magnetic resonance guided focused ultrasound (MRgFUS) thalamotomy targets the ventral intermediate nucleus of the thalamus and has been shown to be safe and effective to treat medication-resistant essential tremors.
