Three-dimensional interactive model of lumbar spinal structures

The application of three-dimensional software to pre-operative magnetic resonance imaging (MRI) data [1] enables 3D models to be reconstructed and embedded in Portable Document Format (PDF) files [2, 3]. We wish to bring readers' attention to a free resource for 3D MRI images that might be useful for interactive demonstration of lumbosacral structures, specifically relevant to neuraxial blockade: http://diposit.ub.edu/dspace/handle/2445/44844?locale=en (English translation top right of screen)...
