[Magnetic resonance tomography controlled focused ultrasound (MRgFUS) for tremor]

Treatment of tremor is a challenge in everyday clinical practice; tremor in movement disorders such as essential or orthostatic tremor (ET, OT) or Parkinson's disease (PD) can rarely be treated sufficiently with oral medication. An alternative to deep brain stimulation is the targeted local lesion of specific structures of the thalamus and basal ganglia by means of transcranial magnetic resonance imaging guided focused ultrasound (MRgFUS). MRgFUS allows to thermally ablate small areas of the brain safely and precisely. MRgFUS treatments are performed without opening of the skull under MRI control ('incisionless surgery'). This minimal invasive procedure can improve the often severely impaired quality of life of the mostly elderly patients on a day to day basis without the need for long in-patient procedures. A sustained effect of the lesion treatment has so far been investigated and documented over 4 years.
