| Abstract |
Objective
Stereotactic MRI is the key investigation for localization in the subthalamic nucleus. The subthalamic nucleus is
prefer target site in movement disorder, epilepsy, etc. We assessed the subthalamic nucleus outline based on MRI images.
Materials and Methods: We have studied stereotactic MRI (Philips, Gyroscan, Netharland) in 34 Parkinsonism patients from
January, 2003 to December, 2006. T1-weighted axial, coronal, stir image and T2-weighted coronal, sagittal sections were provided.
Results
In Koreans, the subthalamic nucleus is small ovoid, mean dorsoventral diameters is 5.42mm (4.0-7.4mm), mean
mediolateral：8.52mm (6.8-10.7mm) rostrocaudal；6.4mm (4.8-8mm). The angle of the horizontal plane：20 degree oblique,
sagittal plane：62.5 degree oblique, frontal plane：59 degree oblique. The reported western subthalamic nucleus is rostrocaudal：
10mm, mediolateral：10.5mm, dorsoventral：7mm, horizontal plane：20° oblique, sagittal plane：35° oblique, frontal plane：
55° oblique.
Conclusions
It is very helpful to know well the subthalamic nucleus outline based on the MRI, it maximized the effect of the
DBS surgery aiding with microelectrode recording. |
