摘要: 目的 探讨采用二维剪切波弹性成像(2D-SWE)技术检查慢性乙型肝炎(CHB)患者,不同取值方法获得的肝脏弹性模量值诊断肝纤维化的效能差异。方法 2019年10月~2022年6月我院诊治的72例CHB患者,行肝活检,根据Scheuer评分将肝纤维化程度分为S0~S4,以Scheuer评分≥S2为显著性肝纤维化。使用Supersonic Aixplorer型彩色多普勒超声诊断仪行2D-SWE检查,分别以5次测量的中位数(方法一)或均值(方法二)为最终检查值。应用受试者工作特征曲线(ROC)并计算曲线下面积(AUC)评估两种取值方法获得的弹性模量值诊断CHB患者肝纤维化和显著性肝纤维化的效能。结果 根据Scheuer评分,肝组织学检查发现肝纤维化S0/S1期31例、S2期19例、S3期12例和S4期10例,其中S2~S4期显著性肝纤维化41例;取值方法一检测的S0/S1、S2、S3和S4期肝脏弹性模量值分别为(6.1±1.2)kPa、(8.1±1.1)kPa、(11.5±1.8)kPa和(20.9±2.5)kPa,与取值方法二检测的(6.0±1.1)kPa、(8.3±1.2)kPa、(11.6±1.5)kPa和(21.1±2.8)kPa比,无显著性差异(P>0.05);两种取值方法检测的肝脏弹性模量值均与肝纤维化呈正相关(r=0.427,P<0.05;r=0.442,P<0.05);以方法一检测的肝脏弹性模量值为6.04 kPa或以方法二检测的6.14 kPa为截断点,它们诊断肝纤维化的AUC分别为0.938和0.956(P>0.05);以方法一检测的肝脏弹性模量值为8.12 kPa或方法二检测的8.25kPa为截断点,它们诊断显著性肝纤维化的AUC分别为0.973和0.968(P>0.05)。结论 以5次测量肝脏弹性模量值的中位数或均值作为2D-SWE检测的最终检查值诊断CHB患者肝纤维化的效能相当。

Abstract: Objective The aim of this study was to compare whether or not different for Young's modulus in predicting liver fibrosis (LF) in patients with chronic hepatitis B (CHB) obtained by two-dimensional shear wave elastography (2D-SWE). Methods 72 patients with CHB were enrolled in our hospital between October 2019 and June 2022, and all underwent liver biopsies. The LF was determined by Scheuer score, and Scheuer score≥S2 was defined as significant LF. Based on 2D-SWE of color Doppler ultrasonography, the Young's modulus was determined by its median value (Method 1) or by its mean value (Method 2). The diagnostic performance of Young's modulus was evaluated by the area under the receiver operating characteristic curve (AUC). Results The liver histopathological examination showed S0/S1 stage in 31 cases, S2 stage in 19 cases, S3 stage in 12 cases and S4 stage in 10 cases, that’s S2-S4 stage in 41 cases in our series; the Young's modulus by method one in patients with S0/S1, S2, S3 and S4 were (6.1±1.2)kPa, (8.1±1.1)kPa, (11.5±1.8)kPa and (20.9±2.5)kPa, all not significantly different compared to(6.0±1.1)kPa, (8.3±1.2)kPa, (11.6±1.5)kPa and (21.1±2.8)kPa obtained by method two (P>0.05); the Young's modulus by method one or two was positively correlated to LF(r=0.427, P<0.05; r=0.442, P<0.05); the AUCs were 0.938 or 0.956 (P>0.05) in predicting LF in patients with CHB as the Young's modulus equal to 6.04 kPa by method one or 6.14 kPa by method two was set as the cut-off-value, and the AUCs were 0.973 or 0.968(P>0.05) in predicting significant LF as the Young's modulus equal to 8.12 kPa by method one or 8.25 kPa by method two was set as the cut-off-value. Conclusion The median or mean value of five measurements of liver elastic modulus as the final parameter by 2D-SWE might have the equivalent diagnostic performance in the diagnosis of LF in patients with CHB.
