An application of MRI in functional stereotactic thalamotomy is presented. To estimate the individual anatomic variations of the thalamus prior to stereotactic thalamotomy, a special study using a proton density image that shows myeloarchitectonic features of the thalamus was performed. The proton density MRI was demonstrated to be very useful to determine the safest trajectory and tentative target point. However, as a detailed functional localization of the thalamic subnuclei cannot be yet obtained by MRI, the final target should be decided on the basis of electrophysiological findings.
本文介绍了磁共振成像（MRI）在功能性立体定向丘脑切开术中的应用。为了在立体定向丘脑切开术前评估丘脑的个体解剖变异，我们进行了一项特殊研究，使用显示丘脑髓鞘构筑特征的质子密度图像。结果表明，质子密度MRI对于确定最安全的手术路径和暂定靶点非常有用。然而，由于目前MRI尚无法获得丘脑亚核的详细功能定位，最终靶点应根据电生理检查结果来确定。
