From: Chronic extradural compression of spinal cord leads to syringomyelia in rat model

Fig. 4

Serial T2-weighted MRIs of rats. a MRI shows the process of central canal dilatation and syringomyelia enlargement. Four weeks after the operation, Sagittal and axial T2-weighted MRI showed the cotton strip was added (red arrow), and syringomyelia enlarged gradually (white arrow). At 8 weeks, syringomyelia was significantly larger than that of 4 weeks. b CSF signal disappears after cotton strip compression in experimental group, while CSF signals in the sham group were obvious. c n/m represents the ratio of the central canal diameter to the spinal cord diameter on MRI in the plane of the largest syrinx. Linear trend of n/m at 4 and 8 weeks. ****P < 0.0001
