超声造影在肝脏局灶性结节增生中的应用

Application of Ultrasound Contrast in Hepatic Focal Nodular Hyperplasia

目的:分析超声造影在肝脏局灶性结节增生(hFNH)中的应用。方法:选取2021年2月-2022年2月华润武钢总医院53例hFNH患者作为研究对象。所有患者均给予常规超声检查及超声造影检查及病理检查。分析所有患者的常规超声检查结果、超声造影检查结果、超声造影图像特征。分析不同病灶直径患者超声造影图像特征及超声造影诊断效果。结果:所有患者平均病灶直径为(5.65±1.68)cm,血流Ⅰ~Ⅲ级。肝左叶9例,肝右叶44例;形态不规则7例,圆形46例;边界清晰47例,模糊6例;等回声3例,高回声8例,稍低回声42例。延迟期有3例为低增强,28例为等高增强,22例为高增强;门静脉期1例为低增强,24例为等高增强,28例为高增强;动脉期均为迅速强化。53例患者中24例显示出中央瘢痕,27例显示出轮辐状动脉,29例显示出离心性增强。病灶直径≥6.0 cm患者中央瘢痕、轮辐状动脉和离心性增强占比均明显高于病灶<6.0 cm患者(P<0.05)。超声造影检出hFNH 51例,检出率为96.23%。结论:给予hFNH患者超声造影检查能够观察病灶图像特征,显示中央瘢痕和轮辐状动脉等表现,检出率好,具有推广价值。

Objective:To analyze the application of ultrasound contrast in hepatic focal nodular hyperplasia (hFNH).Method:From February 2021 to February 2022,53 patients with hFNH in China Resources WISCO General Hospital were selected as the study subjects.All patients were given routine ultrasound examination,ultrasound contrast examination and pathological examination.The routine ultrasound examination results,ultrasound contrast examination results and ultrasound contrast image characteristics of all patients were analyzed.The ultrasound contrast image characteristics in patients with different lesion diameters and the diagnostic effect of ultrasound contrast were analyzed.Result:The average lesions diameter in all patients was (5.65±1.68) cm,and the blood flow was grade Ⅰ-Ⅲ.9 cases in the left lobe of liver and 44 cases in the right lobe of liver;7 cases were irregular shape and 46 cases were circular;47 cases were clear boundary and 6 cases were fuzzy;3 cases were isochoic,8 cases were hyperechoic and 42 cases were slightly hypoechoic.In the delayed phase,3 cases were low enhancement,28 cases were isohigh enhancement and 22 cases were high enhancement;in portal vein phase,1 case was low enhancement,24 cases were isohigh enhancement and 28 cases were high enhancement;the arterial phase showed rapid enhancement.Among the 53 patients,24 cases showed central scars,27 cases showed radial artery,and 29 cases showed centrifugal enhancement.The proportions of central scar,radial artery and centrifugal enhancement in patients with lesion diameter ≥6.0 cm were significantly higher than those in patients with lesion diameter <6.0 cm (P<0.05).A total of 51 cases with hFNH were detected by ultrasound contrast,with a detection rate of 96.23%.Conclusion:Ultrasound contrast examination is given for hFNH patients can observe the image characteristics of the lesions,and show the performance of central scar and radial artery etc.The detection rate is good and it has promotion value.
