【摘要】：目的采用磁共振軸位測(cè)量布-加綜合征(BCS)患者的肝尾狀葉橫徑,并研究其臨床意義。方法搜集本院2015年6月至2016年1月經(jīng)臨床、實(shí)驗(yàn)室及影像學(xué)檢查證實(shí)的BCS患者55例(BCS組)、乙型病毒性肝炎后肝硬化患者30例(乙肝肝硬化組)以及正常對(duì)照者31名(正常對(duì)照組),行磁共振檢查。測(cè)量軸位尾狀葉橫徑、肝右葉橫徑并計(jì)算二者比值,統(tǒng)計(jì)學(xué)方法對(duì)照研究三組各指標(biāo)的差異。繪制受試者工作特征曲線(ROC),并計(jì)算曲線下面積(AUC)。結(jié)果 BCS組尾狀葉橫徑(57.23±15.22)mm,較正常對(duì)照組、乙肝肝硬化組增大(P0.01)。BCS組尾狀葉橫徑與肝右葉橫徑比值0.57±0.15,較正常對(duì)照組、乙肝肝硬化組增大(P0.01)。繪制BCS組對(duì)正常對(duì)照組的ROC曲線,尾狀葉橫徑AUC為0.916,尾狀葉與肝右葉橫徑比值A(chǔ)UC為0.909。當(dāng)尾狀葉橫徑切割點(diǎn)值為42.24 mm時(shí),敏感度為85.8%,特異度為87.1%。當(dāng)尾狀葉與肝右葉橫徑比值切割點(diǎn)值為0.432時(shí),敏感度為83.6%,特異度為83.9%。結(jié)論軸位測(cè)量肝尾狀葉橫徑、尾狀葉橫徑與肝右葉橫徑比值有助于診斷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 鹵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 鹵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.
