Duke CVF Confidence Score: Practical CT Myelogram Application Demonstrated

The Duke CSF-Venous Fistula Confidence Score (DCCS) — a structured reporting tool for grading certainty of CVF detection on CT myelography — is demonstrated via real-world cases in this AJNR video article, aiming to standardize interpretation of a diagnostically challenging SIH…

• Educational video article using a case-based approach to illustrate real-world application of the DCCS, a structured reporting system for CVF identification on CT myelography.
• CVFs are a common cause of spontaneous intracranial hypotension (SIH) but are difficult to detect as they show no contrast pooling — only small contrast volumes in diminutive paraspinal veins.
• No new diagnostic accuracy data are presented; this is a practical demonstration of a previously published scoring system, so performance metrics are not reported in the source.
