Digital Subtraction Myelography for the Detection of Type 1 Spinal CSF Leaks: Evaluation of Temporal Characteristics and Diagnostic Value

DSM demonstrated a high diagnostic yield for type 1 leaks when used as a first-line investigation. We have confirmed the high-flow characteristics of these leaks, suggesting that the high temporal resolution of DSM was ideally suited for their detection, with 1 fps being overall sufficient. A lower Bern SIH score could favor patients for the primary use of dCTM; however, further research may clarify why DSM occasionally misses diagnoses.
