Skull density ratio (SDR) and skull volume in patients with ET are currently considered useful indicators of the successful application of MRgFUS. We compared the clinical outcomes of MRgFUS thalamotomy with SDR above 0.4 and 0.45. We also described patterns of SDR and skull volume in Korean patients with ET who were eligible to be screened for MRgFUS %K Essential tremor %K magnetic resonance-guided focused ultrasound %K MRgFUS %K skull density ratio %K skull volume %U https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6660436/
