Abstract:
Purpose To evaluate the diagnostic value of non-contrast-enhanced MR venography (NCE-MRV) for Budd-Chiari syndrome (BCS). Materials and Methods NCE-MRV and digital subtraction angiography (DSA) examination were performed in thirty-five patients with suspected BCS. The diagnostic agreement between them were compared. The sensitivity, specificity, accuracy, negative predictive value and positive predictive value were also calculated. Results In all 35 patients, 32 were diagnosed as BCS on DSA, and 33 on NCE-MRV. DSA showed inferior vena cava membrane stenosis in 8 patients compared to 10 on NCE-MRV;membrane obstruction in 7 compared to 6 on NCE-MRV, segmental stenosis in 3 compared to 4 on NCE-MRV;segmental obstruction in 10 compared to 10 on NCE-MRV, IVC thrombosis in 5 compared to 5 on NCE-MRV. The sensitivity, specificity, accuracy, negative predictive value and positive predictive value of NCE-MRV in diagnosing BCS were 100.0%, 67.8%, 97.1%, 100.0%and 96.9%, respectively. There was good intra-modality agreement (Kappa=0.89). NCE-MRV also demonstrated intra-hepatic collaterals in 30 patients, extra-hepatic collaterals in 27 cases, and accessory hepatic veins in 25 cases. Conclusion NCE-MRV has excellent diagnostic agreement with DSA in diagnosing inferior vena cava lesion in patients with BCS. It may be used in noninvasive diagnosis.
