Abstract

Fourteen candidates for ablative seizure surgery underwent CT-guided. computer-assisted stereotactic depth electrode implantation and 21 underwent MRI-guided, computer-assisted implantation. A hand-held computer with no graphic capability was used for CT-guided procedures. A computer work station which included a high-resolution color graphics terminal with touchscreen interfacing and software capable of simulating targets and trajectories in single or multiple views was used for MRI-guided procedures. Previous phantom studies done with a 1.5-tesla MR scanner suggested acceptable localization error. Localizing information was obtained in 10 (71.4%) of 14 of the CT-guided implants and in 16 (76.2%) of 21 of MRI-guided cases. In the CT group, 7 (70%) were seizure-free and 8 (80%) were > 90% improved at 1 year follow-up. In the MRI group, 8 (80%) were seizure-free and 9 (90%) were > 90% improved at latest follow-up.
