Atlas-Free Cervical Spinal Cord Segmentation on Midsagittal T2-Weighted Magnetic Resonance Images

Figure 2

A midsagittal T2-weighted MR image (left) and our schematic drawing showing the spinal cord and its surrounding structures (right). The ligaments, including the anterior longitudinal ligament (ALL), the posterior longitudinal ligament (PLL), and the ligamentum flavum (LF), are deliberately thinned, and the internal architectures of intervertebral disks are neglected.
