Summary

The purpose of this research study is to compare two types of Computed Tomography Myelography (CTM) scans, one on the photon counting detector scanner (called PCD-CTM) and the other on the energy integrating detector scanner (called EID-CTM); both of which doctors usually use to diagnose abnormal connections between the cerebrospinal fluid and the venous system, or CSF-venous fistulas. This study will help to see if the newer PCD-CTM scan can find more spinal fluid leaks \[CSF-venous fistulas (CVF)\] than the scan that is normally used (EID-CTM).
