[New progress in the technology of non-invasive diagnosis for small hepatocellular carcinoma].

The diagnosis of small liver cancer is crucial to improving the survival rate of patients. However, traditional diagnostic methods are highly invasive, so the development of non-invasive diagnostic techniques is particularly important. In recent years, non-invasive diagnostic techniques have shown good prospects in the early-stage detection of liver cancer. Therefore, current research focuses on biomarkers, imaging technologies, and artificial intelligence applications. This article aims to review the latest advances in non-invasive diagnostic technologies, discuss their advantages and challenges in clinical application, and look forward to future research directions so as to provide a reference for further improving the diagnosis rate of small liver cancer.
