目的：探讨1.5T MR 扫描仪流入反转恢复(IFIR)序列诊断布-加综合征(BCS)的可行性。方法选取45例 MRI 影像资料齐全、经外科手术或介入治疗确诊的 BCS,比较 IFIR 序列与 DSA 诊断 BCS 的一致性。结果45例患者中,IFIR 序列正确诊断40例(88.9%),其中Ⅰa 型10例,Ⅰb 型14例,Ⅱ型10例,Ⅲ型6例；DSA 正确诊断41例(91.1%),其中Ⅰa 型8例,Ⅰb 型14例,Ⅱ型13例,Ⅲ型6例；两者诊断正确率差异无统计学意义(P>0.05),Spearman 相关分析,具有高度一致性(r=0.853,P<0.001)；但两者在Ⅰa 型和Ⅱ型的分型上差异有统计学意义(P <0.05)。结论1.5T MR IFIR 序列诊断 BCS 与 DSA 有较高的一致性,可作为术前筛查的可靠方法。

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.
