Tremor CT
Introduction
Overview
Overview
Neuroimaging using CT scan may help determine if the tremor is the result of a structural defect or degeneration of the brain.

- Neuroimaging in evaluation of patients presenting with tremor is slowly increasing.
- CT scan can be used to diagnoses cerebellar cause of tremor or can identify stroke, multiple sclerosis, Wilsons disease.
- Precise brain anatomy is required for procedures like stereotactic neurosurgery and deep brain stimulation for accurate electrode placement as there is room for only less than 2-mm tolerance.
- The routine use of single photon emission CT SPECT (123 I-FP-CIT (iodine 123-labelled N-ω-fluoropropyl-2β-carbomethoxy-3β-[4-iodophenyl]nortropane) SPECT (DaTSCAN)) in neuroimaging of the nigrostriatal dopaminergic system helps distinguish essential and dystonic tremors in Parkinson’s disease from neurodegenerative Parkinson’s disease.
