    Abstract:
    Objective: To investigate the application value of three-dimensional liver acceleration volume acquisition (LAVA) multiphase dynamic contrast-enhanced magnetic resonance imaging (MRI) in the detection of accessory hepatic veins (AHVs) in Budd-Chiari syndrome. Methods: A retrospective analysis was performed for the clinical data of 202 patients with Budd-Chiari syndrome who underwent LAVA multiphase dynamic contrast-enhanced MRI and digital subtraction angiography (DSA). MRI or DSA was used to determine the number of AHVs with a diameter of ≥5 mm. With DSA as the gold standard, the Kappa test was used to evaluate the consistency between these two methods in the detection of AHVs. The receiver operating characteristic (ROC) curve was plotted to evaluate the detection rate of AHVs by MRI. The paired chi-square test was used to compare the difference between MRI and DSA in the detection of occluded openings of AHVs. Results: Among the 202 patients, 139 had AHVs detected by MRI, and 63 did not have AHVs detected by MRI; 123 had AHVs detected by DSA, and 79 did not have AHVs detected by DSA. These two methods showed good consistency in the detection of AHVs (κ= 0.631). The area under the ROC curve was 0.868, and MRI had high sensitivity and specificity in the detection of AVHs. MRI detected the occluded openings of 24 AHVs, and DSA detected the occluded openings of 27 AHVs; there was no significant difference in the number of AHVs with occluded openings detected between MRI and DSA (χ2 = 2.2568, P = 0.1330). Conclusion: LAVA multiphase dynamic contrast-enhanced MRI can accurately detect AHVs in Budd-Chiari syndrome and helps to evaluate the patient's condition and select therapeutic methods.
