Liver lesions are often incidentally detected on ultrasound examination and may be incompletely characterized, requiring further imaging. Contrast-enhanced ultrasound (CEUS) was recently approved by the Food and Drug Administration in the United States for liver lesion characterization. CEUS has the ability to characterize focal liver lesions and has been shown to be superior to color Doppler and power Doppler ultrasound in the detection of tumor vascularity. Differentiating benign from malignant liver lesions is essential to characterizing liver lesions. The CEUS imaging characteristics of benign liver lesions are reviewed, including hepatic cysts, hemangiomas, focal fat, focal nodular hyperplasia, hepatocellular adenomas, abscesses, and traumatic lesions.
肝脏病变常在超声检查中偶然发现，可能特征不完整，需要进一步进行影像学检查。对比增强超声（CEUS）最近获得美国食品和药物管理局批准，可用于肝脏病变特征描述。CEUS 具有描述局灶性肝脏病变的能力，在检测肿瘤血管生成方面优于彩色多谱勒和能量多谱勒超声。区分肝脏良恶性病变对于肝脏病变特征描述至关重要。本文回顾了肝脏良性病变的 CEUS 成像特征，包括肝囊肿、血管瘤、局灶性脂肪变性、局灶性结节性增生、肝细胞腺瘤、脓肿和外伤性病变。
