The goal of this study was to investigate the value of a 3D high-resolution sequence with a particular contrast to visualize and delineate pelvic autonomic nerves in a healthy volunteer. Through segmented images and the corresponding 3D reconstruction, we show that our method offers interesting results for the delineation of the hypogastric plexus and the pudendal nerves that are frequently impacted by pelvic surgery. These results are promising for individualized preoperative mapping of autonomic innervation and could provide a valuable support to guide surgeons during interventions when combined with augmented reality.
