Abstract: Liver disease is one of the major problems affecting human health. Ultrasound plays an important role in diagnosis and treatment of diffuse and focal liver diseases. However, conventional ultrasound evaluation is subjective and provides limited information. Artificial intelligence (AI) technology may supplement the disadvantages of conventional ultrasound and has been widely used in the field of ultrasound in liver diseases. To date, remarkable progress has been achieved for the use of AI technology in the diagnosis, assessment of therapeutic efficacy and prognosis prediction of liver diseases. This paper reviews the research progress of ultrasound image⁃based AI technology in the diagnosis and treatment of diffuse and focal liver diseases.

摘要： 肝脏疾病是影响人类健康的主要问题之一。超声在肝脏弥漫性和局灶性病变诊疗中发挥着重要作用，但传统超声评估存在主观性强且提供信息有限的问题。人工智能技术因能弥补传统超声的不足而被广泛应用于肝病超声领域，其在肝脏疾病诊断、疗效评估和预后预测等领域的应用取得了显著进展。本文对近年来国内外基于超声影像的人工智能技术在肝脏弥漫性和局灶性病变诊疗中的研究进展进行综述。
