Objective To explore the feasibility of in-flow inversion recovery (IFIR)sequence of magnetic resonance imaging (MRI)at 1.5T in diagnosis of Budd-Chiari syndrome (BCS).Methods A total of 45 patients with Budd-Chiari syndrome diagnosed by surgery or interventional surgery in our institution were enrolled.The prerequisite of the study was that all medical imaging data including MRI and digital subtraction angiography (DSA)should be integrated.Then,the diagnostic accuracy rates between IFIR sequence and DSA were analyzed and compared.Results Of all 45 patients with BCS,40 (88.9%)were diagnosed accurately by IF-IR sequence,including typeⅠa in 10,typeⅠb in 14,typeⅡ in 10 and type Ⅲ in 6.Meanwhile,41 (91.1%)were diagnosed accu-rately by DSA,including typeⅠa in 8,typeⅠb in 14,typeⅡ in 13 and type Ⅲ in 6.No significant difference was showed in diag-nostic accuracy between two imaging methods (P >0.05).Spearman rank correlation analysis revealed that the diagnostic accuracy of IFIR sequence was highly consistent with that of DSA(r =0.853,P <0.001 ).However,there existed significant difference be-tween two methods in accurate diagnosis of typeⅠa and typeⅡ BCS (P <0.05).Conclusion MRI IFIR sequence at 1.5T is highly consistent with DSA in diagnosis and classification of BCS,which can be used as a reliable method of preoperative screening for BCS diagnosis.
