目的探讨实时剪切波弹性成像在超声诊断肝小静脉闭塞症的临床价值。方法选取临床诊断肝小静脉闭塞症的患者19例为病例组,56例正常健康者为对照组,每例患者均行超声检查及实时剪切波弹性成像,获取每例患者肝脏弹性模量值,两组组间行对照分析,分析其超声表现及组间弹性差异,P<0.05为有统计学意义。结果病例组肝脏弹性模量值范围21.4~43.5kPa,平均值(36.08±5.44)kPa;对照组肝脏弹性模量值范围3.1~7.2kPa,平均值(5.00±0.59)kPa。两组组间有统计学差异(P<0.001)。结论实时剪切波弹性成像可以为临床诊断肝小静脉闭塞症提供参考。
Objective To investigate the clinical value of real-time shear wave elastography in diagnosing hepatic venular occlusive disease by ultrasound. Methods Nineteen patients with venous occlusive disease were selected as case group and 56 normal controls as control group. Ultrasound and real-time shear wave elastography were performed in each patient. The liver elastic modulus Between the two groups, a control study was conducted to analyze the ultrasound findings and the differences between groups in elasticity. P <0.05 was considered statistically significant. Results The liver elastic modulus ranged from 21.4 to 43.5 kPa (36.08 ± 5.44) kPa in the case group and from 3.1 to 7.2 kPa in the control group (mean ± 5.00 ± 0.59 kPa). There was a significant difference between the two groups (P <0.001). Conclusion Real-time shear wave elastography can provide a reference for the clinical diagnosis of hepatic venular occlusive disease.
