摘要
The authors describe dynamic MRI and clinical data after non-invasive treatment of tremor in the upper extremity. Thalamotomy by high-intensity focused ultrasound under MR-guided navigation was performed. A 57-year-old patient with Parkinson's disease underwent treatment with focused ultrasound. MRI of the brain was performed 1 and 48 hours, 47 days, 3 and 6 months later. Features of natural course of focal brain changes after treatment, data of MR tractography necessary for correction of target zone are described. The authors conclude that MR changes are characterized by presence of a focus in the area of focused exposure. Peak severity is observed on the second day after procedure with subsequent regression. MR-based analysis of predictors is promising to forecast treatment outcomes.
