摘要

2成都新世纪妇女儿童医院?影像科??610031 摘要目的分析超声造影（CEUS）鉴别诊断肝脏上皮样血管平滑肌脂肪瘤（EAML）和肝癌的价值。方法回顾性分析40例肝脏EAML患者（EAML组）和40例肝癌患者（肝癌组）的CEUS资料。用Qontrast软件对图像进行定性和定量分析，定性分析结果包括不同实时增强时期的强化程度，定量分析结果包括造影剂抵达时间、峰值强度、达峰时间、增强斜率和开始消退时间。结果常规超声检查显示，与肝癌组比较，EAML组回声程度较低、病灶数量较多（P＜0.05），两组血流信号强度、病灶位置和病灶边缘特点的比较无统计学差异（P＞0.05）。与肝癌组比较，EAML组向心性增强例数较多，延迟相强化程度较低（P＜0.05）。两组动脉相和门脉相增强程度比较无统计学差异（P＞0.05）。与肝癌组比较，EAML组峰值强度较高，而达峰时间和开始消退时间较短（P＜0.05）。两组增强斜率和抵达时间的比较无统计学差异（P＞0.05）。结论肝脏EAML和肝癌存在不同的血流灌注特征，CEUS对鉴别诊断这两种疾病有一定价值。

Abstract

ABSRACT Objective To analyze the value of CEUS in differential diagnosis of liver epithelioid angiomyolipoma (EAML) and hepatocellular carcinoma. Methods The CEUS data of 40 patients with EAML and 40 patients with hepatocellular carcinoma were analyzed retrospectively. Qualitative and quantitative analysis of images was carried out with Qontrast software. The results of qualitative analysis included the degree of enhancement in different real-time enhancement periods. The results of quantitative analysis included the arrival time

peak intensity

peak time

enhancement slope and the start time of fading. Results Compared with the hepatocellular carcinoma group

the echo degree of EAML group was lower and the number of lesions was more (P＜0.05). There was no significant difference between the two groups in the intensity of blood flow signal

the location of focus and the edge of focus (P > 0.05). Compared with hepatocellular carcinoma group

there were more cases of centripetal enhancement in EAML group

and the degree of delayed phase enhancement was lower (P < 0.05). There was no significant difference between the two groups in the enhancement degree of arterial phase and portal phase (P > 0.05). Compared with the hepatocellular carcinoma group

the peak intensity of EAML group was higher

while the peak time and the beginning time of regression were shorter (P < 0.05). There was no significant difference in enhancement slope and arrival time between the two groups (P > 0.05). Conclusion There are different blood perfusion characteristics between EAML and hepatocellular carcinoma. CEUS is valuable for the differential diagnosis of these two diseases.
