Abstract

Introduction: Stereotactic surgery has become the surgical treatment of choice for medication-refractory Parkinson’s disease, essential tremor, dystonia, pain, etc. MRI is accurate enough for preoperative stereotactic planning and can be used as an accepted imaging modality for localization of functional targets. Materials: We assessed the thalamic distance in the 39 Parkinsonism patients based on the MRI. Male to female ratio was 6：7, mean age was 57.4 years (35-76 years).
Results
In Schalten-Wahren Atlas, mean thalamic distance is 31mm. In our study, the mean right thalamic distance was 31.5 (27.4-35.7)mm*16.96 (12.9-21.4)mm, mean left thalamic distance was 31.84 (28.31-35.8)mm*16.73 (14.4-19.8)mm.
Conclusion
MRI is an acceptable imaging modality to be used along for target localization in stereotactic surgery. There was no difference in the thalamic distance between Eastern and Western, we can operated aiding with the Western Brain Atlases.

Key Words: Stereotactic surgery, Thalamic distance, Atlases.
