Prone Digital Subtraction Myelography versus Dynamic CT Myelography for Detecting Definite Type 1 CSF Leak in Spontaneous Intracranial Hypotension

Key Points

This research aims to compare prone digital subtraction myelography (DSM) and dynamic CT myelography (dCTM) for detecting Type 1 cerebrospinal fluid (CSF) leaks.
Compared diagnostic yields of prone DSM and dCTM for Type 1 CSF leaks.
Assessed radiation safety associated with both imaging techniques.
Evaluated expertise requirements for each modality.
Both DSM and dCTM showed high diagnostic accuracy in localizing leaks.
DSM presented a significant advantage in terms of lower radiation exposure.
Prone DSM is recommended as a first-line diagnostic tool with dCTM as a backup.

Abstract

Prone DSM and dCTM demonstrated comparably high diagnostic yields for localizing Type 1 leaks. However, DSM offered a significant advantage in radiation safety. When available and supported by appropriate expertise, prone DSM may be considered as a preferred first-line modality, with dCTM serving as a complementary option.
