Dynamic CT myelography: a technique for localizing high-flow spinal cerebrospinal fluid leaks.

Author information

Department of Radiology, Mayo Clinic, Rochester, Minnesota 55905, USA.


In some patients with spontaneous spinal CSF leaks, leaks are numerous or tears are so large that extrathecal myelographic contrast material is seen at multiple levels during CT, making identification of their source impossible. This study introduces a dynamic CT myelographic technique that provides high temporal and spatial resolution. In this technical note, we describe the utility of this technique in four patients with challenging high-flow spinal CSF leaks.
