FIESTA序列对Budd-Chiari综合征下腔静脉病变的诊断价值

The value of FIESTA sequence in the diagnostis of inferior vena cava lesions with Budd-Chiari syndrome

目的探讨FIESTA序列对Budd-Chiari综合征(BCS)下腔静脉病变的诊断价值。材料与方法回顾性分析51例临床诊断为BCS的患者的下腔静脉病变情况,以DSA为诊断金标准,评估FIESTA序列对下腔静脉病变的诊断能力,包括检出静脉病变的敏感度、特异度、诊断准确度,显示下腔静脉血栓、下腔静脉瘤的能力。结果 MRI诊断准确有41例,灵敏度为97.61%、特异度为55.56%、准确度为90.20%;发现下腔静脉血栓8例,下腔静脉瘤样扩张4例。结论FIESTA序列在显示BCS的下腔静脉中具有直观、准确率较高、无需对比剂的优点,可作为诊断BCS下腔静脉病变的常规序列。

Objective： To study the FIESTA sequence in the assessment of the inferior vena cava lesions in patients of Budd-Chiari syndrome（BCS）. Materials and Methods： To retrospectively analyze the inferior vena cava stenosis of 51 patients diagnosed with BCS, with the DSA as the gold standard for diagnosis, to assess the utility of FIESTA sequence in the diagnosis of inferior vena cava lesions, including the sensitivity, specificity, diagnostic accuracy in detecting lesions and the ability in displaying inferior vena cava thrombosis and the inferior vena cava varicosity. Results： Forty-one cases were correctly diagnosed by MRI, the sensitivity was 97.61%, specifi city 55.56%, accuracy 90.20%. Eight cases of inferior vena cava thrombosis and 4 cases of inferior vena cava varicosity were found. Conclusion： The FIESTA sequence has the characteristics of intuitive and high accuracy to display inferior vena cava lesions of BCS, and without contrast medium. So the FIESTA sequence can be used as regular sequence to diagnose inferior vena cava lesions of BCS.
