【摘要】：目的采用磁共振轴位测量布-加综合征(BCS)患者的肝尾状叶横径,并研究其临床意义。方法搜集本院2015年6月至2016年1月经临床、实验室及影像学检查证实的BCS患者55例(BCS组)、乙型病毒性肝炎后肝硬化患者30例(乙肝肝硬化组)以及正常对照者31名(正常对照组),行磁共振检查。测量轴位尾状叶横径、肝右叶横径并计算二者比值,统计学方法对照研究三组各指标的差异。绘制受试者工作特征曲线(ROC),并计算曲线下面积(AUC)。结果 BCS组尾状叶横径(57.23±15.22)mm,较正常对照组、乙肝肝硬化组增大(P0.01)。BCS组尾状叶横径与肝右叶横径比值0.57±0.15,较正常对照组、乙肝肝硬化组增大(P0.01)。绘制BCS组对正常对照组的ROC曲线,尾状叶横径AUC为0.916,尾状叶与肝右叶横径比值AUC为0.909。当尾状叶横径切割点值为42.24 mm时,敏感度为85.8%,特异度为87.1%。当尾状叶与肝右叶横径比值切割点值为0.432时,敏感度为83.6%,特异度为83.9%。结论轴位测量肝尾状叶横径、尾状叶横径与肝右叶横径比值有助于诊断BCS。
[Abstract]:Objective to measure the transverse diameter of caudate lobe of liver in patients with Budd-Chiari syndrome (BCS) by magnetic resonance imaging (MRI) and to study its clinical significance. 55 patients with BCS confirmed by laboratory and imaging examination, 30 patients with posthepatitic cirrhosis of hepatitis B (hepatitis B cirrhosis group) and 31 normal controls (normal control group) were examined by magnetic resonance imaging. The transverse diameter of axonal caudate lobes was measured. The transverse diameter of the right lobe of the liver and the ratio of the two were calculated. The statistical method was used to compare the differences between the three groups. The operating characteristic curve was drawn and the area under the curve was calculated. Results the transverse diameter of caudate lobe in the BCS group was 57.23 卤15.22 mm, which was higher than that in the normal control group. The ratio of transverse diameter of caudate lobe to right lobe of liver in liver cirrhosis group was 0.57 卤0.15, which was larger than that in normal control group. The ROC curve of BCS group to normal control group was drawn. The transverse diameter of caudate lobe was 0.916, the ratio of transverse diameter of caudate lobe to right lobe of liver was 0.909.When the cutting point of caudate lobe was 42.24mm, the sensitivity was 85.8 and the specificity was 87.1. When the ratio of transverse diameter of caudate lobe to right lobe of liver was 0.432, Conclusion measuring the transverse diameter of the caudate lobe and the ratio of the transverse diameter of the caudate lobe to the right lobe of the liver in axial position is helpful for the diagnosis of BCS.
