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

Figure 7

Segmentation results in nearly normal and severely degenerated cervical spines. The left half of each image is the original image containing the cord (gray) and its surrounding cerebrospinal fluid region (white). The right half of each image is the segmentation result. Erroneously classified pixels are shown in white. Components of the epidural space are also shown in some nonstenotic areas, but they are clinically irrelevant.
