Evaluation of essential tremor with multi-voxel magnetic resonance spectroscopy
The pathologic substrate of essential tremor (ET) remains unknown. The authors studied 10
patients with ET and 10 volunteers using a multislice MR spectroscopy imaging sequence.
Left and right cerebellar hemisphere NAA/CR and NAA/Cho ratios were significantly smaller
in the ET patients than healthy subjects. The authors' data suggest that the decreased
NAA/Cr and NAA/Cho ratios within the cerebellum may represent an abnormality in
neuronal function.
