Abstract

We present a method to reduce the geometric distortion in fast spin echo (FSE) images to levels appropriate for guiding stereotactic pallidotomy. We quantify the accuracy of FSE- guided target localization before and after correction using a cadaver head model. These results strongly suggest that stereotactic pallidotomy can be performed using MR and stimulation responses alone, thus avoiding the morbidity associated with pallidotomy and the costs of x-ray apparatus and personnel during surgery. This method, however, must be tested further and validated clinically before it can be applied.
