Nervous System Exploration Using Tractography To Enhance Pelvic Surgery

Abstract :

Pelvic surgery raises the challenge of preser- vation of nerves that handle urinary, gen- ital and digestive functions, especially in situations where these structures may be modi- fied by tumors or malformations. Recent works on 3D nerve visualization, that rely on cadavers dissections [1, 3] or intra-operative use of probes detecting myelin-binding fluorophores [5], do not provide pre- or post-operative analysis of the pelvic nervous anatomy. Magnetic reso- nance neurography as in [12] requires a slice by slice manual segmentation of the nerves. Dif- fusion MRI, associated with tractography algo- rithms, is currently the only technique allow- ing for in-vivo exploration of the nervous net- work [2] with no need for manual nerve segmen- tation. In contrast to brain imaging that moti- vated a lot of work, only few studies focus on pe- ripheral nerves visualization [9, 10, 14]. In this paper, we propose a method for pelvic tractog- raphy analysis based on patient-specific organ segmentation. It is demonstrated with promis- ing results on a healthy adult subject.
