All patients underwent postoperative MRI which showed excellent decompression of cord and duralsac in all cases.
2
Conclusion: Quantitative assessment of sagittal duralsac diameters is comparable between lumbar myelography and positional MR imaging.
3
A small but statistically significant positional dependence of the duralsac diameter was found in the lower lumbar spine.
4
The midsagittal diameter of the duralsac was measured at the level of the disks on MR images and myelograms.
5
Dynamic cervical magnetic resonance imaging was used, revealing the classic findings of epidural venous plexus dilation and anterior displacement of the duralsac.
