Imaging Findings in MR Imaging-Guided Focused Ultrasound Treatment for Patients with Essential Tremor

Abstract

MR imaging-guided focused sonography can accurately ablate a precisely delineated target, with typical imaging findings seen in the days, weeks, and months following the treatment. Tremor control was optimal early when the lesion size and perilesional edema were maximal and was less later when the perilesional edema had resolved.
