3-D brain mapping could sharpen ultrasound treatment for hand tremors

This study tests whether using 3-D tractography—a detailed brain imaging method—can make focused ultrasound ablation safer and more effective for people with essential tremor. Twenty-four adults with moderate to severe tremor that hasn't responded to medication will receive the procedure. Researchers will track side effects and tremor improvement over three months to see if this advanced imaging helps target the right brain area more precisely.
