Transcranial MR-guided high-intensity focused ultrasound ablation of the ventral
division of the ventral lateral posterior thalamic nucleus (VLpv) is a
promising, minimally invasive treatment method for essential tremor. We report
our initial clinical experience in 11 patients, and correlate clinical outcome
with lesion size, location, and thermal dose during treatment. We found a
correlation between clinical outcome at 1 year follow-up and lesion size (r = 0.73), as well as thermal dose in the
VLpv (r = 0.65).
