【摘要】：目的:探讨实时超声造影技术在诊断肝脏占位性病变中的价值。方法:对本院2014年3月至2016年2月收治的90例肝脏占位性病变患者行超声造影技术,并实时观察超声造影过程。结果:原发性肝癌的动脉相早期可迅速增强,动脉后期可迅速消退;胆管细胞癌的动脉相周边强化,门脉相及延迟相迅速消退;转移性肝癌动脉相周边多数呈环状增强,延迟相迅速消退;肝脓肿动脉相周边强化,延迟相及门脉相表现为低回声;肝血管瘤首先增强周边,由周边向内部呈结节样填充;肝硬化结节及不均质脂肪肝动脉相均未有显著增强,延迟相、门脉相与周边肝实质同步增强,呈现等回声,不显示病灶;局灶性结节性增生,首先将增强结节内的粗大动脉,随后造影剂将显现为轮辐状,并由中心向外周呈放射状充填;肝腺瘤动脉相迅速增强,门脉相呈等增强,延迟相呈现低增强。超声造影诊断正确率为87.2%,未确诊或漏诊率为12.8%。结论:实时超声造影技术能够提高肝脏占位性病变的诊断正确率,具有较高的临床应用价值。
[Abstract]:Objective: to evaluate the value of real-time contrast-enhanced ultrasonography in the diagnosis of hepatic space-occupying lesions. From March 2014 to February 2016, 90 patients with hepatic space occupying lesions were treated with contrast-enhanced ultrasonography. Results: the arterial phase of primary liver cancer could be rapidly enhanced at the early stage, and the arterial phase could be rapidly dissipated at the later stage. Peripheral enhancement of arterial phase, portal phase and delayed phase of cholangiocarcinoma disappeared rapidly. Most of the arterial phase of metastatic liver cancer showed annular enhancement and the delayed phase subsided rapidly. Hepatic abscess showed peripheral enhancement in arterial phase, hyperechoic in delayed phase and portal phase. The hemangioma of the liver was firstly enhanced and filled with nodules from the periphery to the interior. The hepatic cirrhosis nodules and heterogeneous fatty liver arteries were not significantly enhanced, delayed phase, portal phase and peripheral hepatic parenchyma enhanced synchronously, showing isoechoic, no focus; In focal nodular hyperplasia, the coarse arteries in the nodules were first enhanced, and then radially filled from the center to the periphery. The arterial phase of hepatic adenoma was enhanced rapidly, the portal vein was isoenhancement and the delayed phase was low enhancement. The diagnostic accuracy of contrast-enhanced ultrasound was 87.2%. Conclusion: Real-time contrast-enhanced ultrasonography can improve the diagnostic accuracy of hepatic space occupying lesions and has high clinical application value.
