Abstract

An anatomic variability study of the spatial relationship between the imaged globus pallidus. the optic tract, and the anterior and posterior commissures was performed using T1-Weighted gradient echo three-dimensional volume acquisition MRI of 20 patients. Imaging data were resized, reformatted, and manually segmented for the above structures, and mean values and standard deviations for their medial, superior, lateral, and inferior limits determined. Findings demonstrate that the globus pallidus can be consistently and reliably imaged by MRI. that direct stereotactic targeting of this structure can account for normal anatomic variability which may be as much as several millimeters, and that the risk of injury to the optic tract may be reduced with this technique.
