Maximizing the Conspicuity of CSF-Venous Fistulas on CT Myelography: Assessment of Contrast Density and Timing Effects
Both contrast density and time influence conspicuity of CVFs on CTM; however, the greater relative impact of density suggests that myelogram technique should prioritize maximization of contrast density for optimal visualization of CVFs. Positioning strategies to increase local contrast pooling may improve CVF detection more effectively than timing adjustments alone.
