“…In fact, experience in evaluating DAVF with C-arm CT, as recently described by Hiu et al 17 and Lasjaunias et al, 33 helps generate confidence in evaluating CTA correlates of classic angiographic findings. 32 The current series supports findings of earlier reports that suggest that DAVFs associated with PT often involve the sigmoid sinus.…”

“…Various imaging strategies have been proposed, including MR imaging, MRA, MRV, carotid sonography, CTA/CTV, and DSA. [12][13][14][15][16][17] None of these studies have well-defined test characteristics. Conventional angiography remains the most sensitive and specific technique for diagnosing DAVF.…”

“…31 Spatial resolution is lower on images of 3T TOF MRA than DSA, and 3T TOF MRA does not provide the temporal resolution of the vascular flow dynamics. Consequently, information of 3T TOF MRA regarding venous anatomy is inferior to that of DSA, and 3T TOF MRA cannot replace DSA at the treatment planning stage.…”

Purpose: We compared gross characterization of intracranial dural arteriovenous fistulas (DAVFs) between unenhanced 3-tesla 3-dimensional (3D) time-of-flight (TOF) magnetic resonance angiography (MRA) and digital subtraction angiography (DSA).Methods: We subjected 26 consecutive patients with intracranial DAVF to unenhanced 3T 3D TOF MRA and to DSA. Two independent sets of observers inspected the main arterial feeders, fistula site, and venous drainage pattern on MRA and DSA images. Interobserver and intermodality agreements were assessed by k statistics.Results: Interobserver agreement was excellent for fistula site (¬ = 0.919; 95% confidence interval [CI], 0.805 to 1.000), good for main arterial feeders (¬ = 0.711; 95% CI, 0.483 to 0.984), and very good for venous drainage (¬ = 0.900; 95% CI, 0.766 to 1.000). Intermodality agreement was excellent for fistula site (¬ = 0.968; 95% CI, 0.906 to 1.000) and good for main arterial feeder (¬ = 0.809; 95% CI, 0.598 to 1.000) and venous drainage (¬ = 0.837; 95% CI, 0.660 to 1.000).Conclusion: Gross characterization of intracranial DAVF was similar for both imaging modalities, but unenhanced 3T 3D TOF MRA cannot replace DSA.

“…[14][15][16][17][18][19] It is, nonetheless, possible that slow-flowing CVR or fistulas may be missed by using these techniques, given the lack of selective arterial injection and lesser temporal resolution compared with DSA. This situation has recently been encountered in a series of DAVFs evaluated by dynamic CTA 14 and highlights the persisting role of conventional angiography in DAVF characterization.…”

SUMMARY:In this short report, we describe the potential contribution of SWI in the noninvasive evaluation of DAVFs. SWI images were compared with DSA for the identification of the location of the fistulous point, the presence of CVR, and the presence of the PPP. In 5 of 6 patients, it was possible to identify the fistulous locations depicted as hyperintensity within venous structures. Cortical venous reflux was underestimated on SWI in 3 cases of robust CVR and not identified in 2 cases of less severe CVR. The PPP seen on angiograms correlated anatomically with increased number, caliber, and tortuosity of hypointense veins seen on SWI. Furthermore, SWI was superior to conventional MR imaging in the detection of these dilated veins. These preliminary results suggest an important role for SWI in the detection and assessment of the complex hemodynamics associated with DAVFs.ABBREVIATIONS: AP ϭ anteroposterior; CVR ϭ cortical venous reflux; DAVF ϭ dural arteriovenous fistula; mIP ϭ minimum intensity projection; MIP ϭ maximum intensity projection; PPP ϭ pseudophlebitic pattern
