Overview

Essentially an MRI is not helpful in diagnosing most common causes of tremor, it can help diagnose some less common causes of tremor including, cerebellar lesion, stroke, multiple sclerosis , Wilsons disease. It may help determine if the tremor is the result of a structural defect or degeneration of the brain. Magnetic resonance guided focused ultrasound (MRgFUS), is a noninvasive focused ultrasound ablative thalamotomy procedure used to treat essential tremor.
