This study aims to obtain finer details of tissues surrounding a lead in the pelvis using a combination of high resolution anatomical MRI sequences and diffusion tensor imaging (DTI). Diffusion tensor imaging is a non-invasive technique sometimes described as fibre tractography that enables visualization of the pathways and integrity of nerves. In this feasibility study we plan to use DTI to assess the sacral plexus and its peripheral nerves. A computational model will be constructed by superimposing SNS lead from a CT scan onto the DTI imaging to map out the electrode position. It is hoped that this study will lead to better understanding of both therapeutic and adverse stimulation effects and enable patient-specific adjustments of stimulation parameters.
