Abstract: Liver is an important solid organ in our body. Ultrasound provides a sensitive tool to detect abnormal lesions in the liver, whether diffuse lesions or focal lesions. In recent years, the integration between artificial intelligence (AI) and medical imaging has become a research hotspot. After being trained by big data, AI models can automatically recognize and analyze the input data, and output predictions, which assist in clinical diagnosis and treatment. Therefore, this paper thoroughly summarizes the research advances in AI-assisted ultrasound diagnosis of liver lesions.
