Backgroud - Deep brain stimulation (DBS) involves placing electrodes within specific deep brain nuclei. For movement disorders the most common indications are tremors, Parkinsons disease and dystonias. Surgeons mostly employ MR imaging for preoperative target selection. MR field geometrical distortion may contribute to target-selection error in the MR scan which can contribute to error in electrode placement. Methods - In this paper we compared the STN target planning coordinates in six parkinsonian DBS patients. Each patient underwent target planning in IT and 3T MRI. We statistically compared and analysed the target-, and the fiducial coordinates in two different magnetic fileds. Results - The target coordinates showed no significant differences (Mann-Whitney test, p > 0.05), however we found significant difference in fiducial coordinates (p < 0.01), in 3T MRI it was more pronounced (mean ± SD: 0.8 ± 0.3 mm) comparing to IT (mean ± SD: 0.4 ± 0.2 mm). Conclusion - Preliminary results showed no significant differences in planning of target coordinates comparing IT to 3T magnetic fields.
