摘要: 肝细胞癌是最常见的原发性肝癌类型,整体预后较差。超声造影在肝细胞癌的诊断、疗效评估及预后判断等方面具有重要价值。本文系统梳理了超声造影在肝细胞癌领域的文献特征、研究热点与前沿进展。该领域年发文量总体呈稳步增长趋势,中国在发文总量上居全球首位。高被引文献高度集中于临床指南与标准化规范。关键词分析结果显示,该领域研究热点主要包括肝细胞癌诊断与标准化评估、鉴别诊断、局部治疗后疗效评价及预后预测。同时,微血管侵犯、人工智能及超分辨超声等可能成为当前领域的前沿方向。其中,人工智能可应用于肝细胞癌辅助诊断、肿瘤生物学特征评估及预后预测,而超分辨超声可突破衍射极限,实现肝脏微血管精确成像。当前,肝细胞癌超声造影已有坚实的研究基础,具有较强的临床实践导向。未来基于超声造影的人工智能模型及超分辨超声等新技术有望进一步推动肝细胞癌精准诊疗的发展。Abstract: Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and has a poor overall prognosis. Contrast-enhanced ultrasound (CEUS) plays a crucial role in the diagnosis, treatment response evaluation, and prognostic evaluation of HCC. This article systematically reviews the literature characteristics, research hotspots, and frontier advances of CEUS in the field of HCC. There has been a gradual increase in annual publication volume in this field, with China ranking first globally in the total number of publications. Highly cited articles mainly focus on clinical guidelines and standardized protocols. Keyword analysis shows that the main research hotspots in this field include the diagnosis and standardized assessment of HCC, differential diagnosis, treatment response evaluation after local therapy, and prognostic prediction. Meanwhile, microvascular invasion, artificial intelligence (AI), and super-resolution ultrasound (SRUS) may be emerging as cutting-edge frontiers in this field. Specifically, AI can be used for the auxiliary diagnosis of HCC, the evaluation of tumor biological characteristics, and prognostic prediction, and SRUS can overcome the acoustic diffraction limit to achieve precise microvascular imaging of the liver. Currently, a solid foundation has been established for the research on CEUS in HCC, showing a strong orientation toward clinical practice. In the future, emerging technologies such as CEUS-based AI models and SRUS are expected to further promote the development of precise diagnosis and treatment for HCC.
