Figure 5

Demonstration of the quantitative T2 approach: myelin water fraction (MWF) images from a healthy control and a patient with cervical spondolysis. In the left panels, T2-weighted and MWF maps of a healthy control are presented. The GM has a low MWF while the white matter appears brighter. In the center and right panels, a patient with cervical spondolysis is shown; the disc between C3–C4 is making contact with the spinal cord. The MWF maps at the site of spondolysis show a change in the myelin water fraction in each column, while, caudal to the lesion, the MWF maps appear normal.
