Impact of Skull Density Ratio on Efficacy and Safety of Magnetic Resonance–guided Focused Ultrasound Treatment of Essential Tremor

An international group of clinicians from 16 medical centers collaborated to determine whether skull density ratio (SDR) had an impact on safety or efficacy for patients with essential tremor who had been treated with focused ultrasound ablation. The retrospective analysis of 189 patients assessed whether the SDR measurements correlated with ease of achieving a peak voxel temperature of 54°C – the rate of the most severe procedure-related adverse event – and improvement in tremor scores one year after treatment. Which patients have the optimal SDR for this procedure? See the Journal of Neurosurgery >
