Description
<p>Introduction: Magnetic resonance imaging (MRI) and spinal digital subtraction angiography (DSA) are considered the gold standard for the screening and diagnosis of spinal dural arteriovenous fistula (SPDAVF). However, the flow-void signals of abnormal vessels are not always reported, even when spinal cord edema is detected with the MRI, rendering the diagnosis in such cases difficult. Similarly, although selective spinal DSA is useful for the definite diagnosis of SPDAVF, it can be a lengthy procedure requiring technical proficiency. Here, we introduce an effective diagnostic procedure with MRI (3T MRI 3D T2 Cube), followed by reconstruction of the 3D-CTA (64 row multistring detector CT).</p><p>Material and Methods: A total of 15 consecutive cases of SPDAVF present in the departmental database from April 2006 to June 2017 were reviewed in this study. Of these, we enrolled 5 patients who conducted the 3T MRI 3D T2 Cube and/or 3D-CTA with the analysis application VINCENT®.</p><p>Result: Of the 5 SPDAVF cases analyzed, 4 showed flow-void signals around the spinal cord in the 1.5T MRI T2WI. In contrast, all cases showed engorged vessels around the spinal cord with the 3D-CTA reconstructed VINCENT® image. The entry point of the influx vessels can be easily identified, resulting in simple and efficient selective spinal DSA. Furthermore, the 3D-CTA reconstructed image was helpful as a surgical simulation tool.</p><p>Conclusion: The diagnostic procedure of the 3T MRI 3D T2 Cube followed by the reconstructed 3D-CTA image markedly contributes to the diagnosis of SPDAVF and the identification of the entry point of the influx vessels and is helpful for both efficient spinal DSA and surgical simulation.</p>
