Brain plasticity induced by magnetic resonance-guided focused ultrasound correlates with tremor improvement in essential tremor: a prospective cohort study

ET = essential tremor; MRgFUS = magnetic resonance-guided focused ultrasound; GMV = gray matter volume; VBM = voxel-based morphometry; HCs = healthy controls; VIM = ventralis intermedius; CAT12 = Computational Anatomy Toolbox; SUIT = Spatially Unbiased Infratentorial Template; CRST = Clinical Rating Scale for Tremor; FWHM = full-width at half-maximum; CTC = cerebello-thalamo-cortical; GPi = internal globus pallidus; GPe = external globus pallidus; STN = subthalamic nucleus; FWE = family-wise error; FDR = false discovery rate; DRTC = dentato-rubro-thalamo-cortical; STG = superior temporal gyrus; op-1y = one year postoperatively; DBS = deep brain stimulation; PCs = Purkinje cells.
