多层螺旋CT及图像后处理重建技术在布-加氏综合征诊断中的应用

目的：探讨多层螺旋CT（MSCT）及图像后处理重建技术在布一加氏综合征诊断中的临床应用价值。方法：收集近两年来经超声及临床证实的布一加氏综合征55例．均使用64排多层螺旋CT机行中上腹部CT平扫及增强扫描．并采用多平面重组（MPR）、最大密度投影（MIP）等图像后处理重建技术，以显示肝静脉及下腔静脉肝内段血管形态。结果：图像后处理技术的重建图像中显示肝静脉及下腔静脉肝内段均有不同程度的受压、狭窄征象；同时在平扫及增强扫描图像中，布-加氏综合征在影像表现上有不同程度的肝硬化、脾大、腹水、食管胃底静脉曲张等。结论：多层螺旋CT（MSCT）图像后处理重建技术显示肝静脉及下腔静脉血管形态良好，具有重要的诊断价值及临床指导意义。

Clinical Application Value of MSCT & Reconstruction Technique on Budd-chiari Syndrome Diagnosis

Objective To explore the clinical implications of MSCT and reconstruction technique of Budd-chiari syndrome diagnosis. Methods Hepatic vein and intrahepatic inferior vena cava vascular morphology were shown by 55 cases of Budd-ehiari syndrome with confirmed by ultrasound and clinic in nearly two years, which used the 64-row MSCT examination in upper abdominal and enhanced scan, and reconstruction techniques that is included MPR and MIP etc. The compression and narrow signs of hepatic vein and intrahepatic inferior vena cava can be seen by reconstruction imaging with post-processing techniques, at the same time, these phenomena that are varying degrees of cirrhosis, splenomegaly, ascites, and esophageal varices can be displayed by Budd-chiari syndrome imaging in plain and enhanced CT images, Conclusion MSCT reconstruction techniques can be used to manifest clearly the appearance of hepatic vein and inferior vena cava, and have important diagnostic value and clinical significance.
