Personalized Lumbosacral Spinal Nerve Roots 3D Reconstruction and Computer Simulation for Spinal Cord Stimulation

Motivation: Spinal cord stimulation requires personalized 3D reconstructed model to address challenges arising from individual variability. Goal(s): This study aims to image the entire spinal cord with lumbosacral nerve roots and propose a method for reconstructing a 3D model for simulation. Approach: Three MRI sequences were collected for reconstruction and nerve roots annotation. Then the 3D spinal cord model was reconstructed using a custom interpolating algorithm guided by anatomical rules. Results: A tailored imaging protocol and reconstruction method designed for the spinal cord and its nerve roots have been proposed, resulting in a 3D personalized spinal cord model. Impact: The protocol offers an effective guide for researchers and clinicians conducting spinal cord and nerve roots imaging. Additionally, it enables the creation of personalized computational spine models with nerve roots and rootlets from MRI images, facilitating simulation studies.
