肝血管瘤超声造影表现

Contrast-enhanced ultrasound manifestations of hepatic hemangioma

目的回顾性研究肝血管瘤超声造影(CEUS)的表现,总结肝血管瘤超声造影检查的表现特征。方法通过运用对比脉冲序列成像(CPS)技术对17例肝血管瘤(共21个病灶)进行超声造影检查,从而观察其动脉期、门脉期及延迟期的增强表现。结果超声造影肝血管瘤主要表现为动脉期或门脉早期周边环状、结节状增强,门脉期缓慢向心性充填,延迟期为最大增强。结论肝血管瘤在肝脏实时超声造影检查中具有特异性表现,可提高诊断准确率。

Objective To analyze the contrast-enhanced ultrasound （CEUS） manifestations of hepatic hemangioma retrospectively and summarize the characteristics of CEUS manifestations. Methods The contrast pulse sequence （CPS） technique was used to conduct the CEUS examination of 17 patients with hepatic hemangioma （21 lesions） in order to observe the enhanced manifestations in atrial phase, portal vein phase and delayed phase. Results The main manifestations of hepatic hemangioma in CEUS were peripheral cyclic and nodular enhancement in atrial phase or early portal vein phase, chronic centripetal filling in portal vein phase, and largest enhancement in delayed phase. Conclusion Hepatic hemangioma has specific manifestations in the real time contrast-enhanced ultrasound, which can improve the diagnostic accuracy.
