摘要: Purpose To compare 3D liver acceleration volume acquisition (LAVA) and digital subtraction angiography (DSA) for evaluating the presence of accessory hepatic veins (AHV) in Budd-Chiari syndrome (BCS). Materials Methods This was a retrospective study 228 patients with BCS who underwent 3.0T magnetic resonance imaging (MRI) LAVA sequence. Two reviewers noted AHV: openings located inferior vena cava (IVC), caliber, angle entering into IVC. MRI results were compared to DSA. Kappa statistics calculated quantify intrareader variability detecting AHVs. Results On MRI, 63 demonstrated no AHV on images, 70 had one AHV, 62 two AHVs, 26 three six four patient five AHVs (P < 0.05 vs. DSA). The mean caliber 8.3 ± 4.0 mm 9.9 3.2 DSA 0.001). Among 301 there 140 acute angles (46.5%), 71 right (23.6%), 90 obtuse (29.8%). prevalence 54.8% (125/228), while 165 patients, 72.4% (165/228) = methods concordant only 116/228 (50.9%) patients. kappa coefficient good consistency all documented findings (κ 0.626 κ 0.65 angles). Conclusion More visible sequences than conventional DSA. Level Evidence: 4 J. Magn. Reson. Imaging 2017;45:401–409.
