Prognostic value of brain tissues’ volumes in patients with essential tremor treated with MRgFUS thalamotomy

•Brain tissues interposed between the Focused Ultrasound transducers and the Thalamic Ventral Intermediate Nucleus (VIM) influence the effectiveness of a satisfactory target temperature.•Supratentorial – Grey Matter is positively correlated with the Accumulated Thermal Dose (ATD) in the VIM.•Supratentorial – Cerebrospinal Fluid negatively correlated with the Accumulated Thermal Dose in the VIM.•Brain tissue seems to have more effect on the ATD than the Skull Density Ratio (SDR).
