Research Progress on Contrast-Enhanced Ultrasound (CEUS) Assisted Diagnosis and Treatment in Liver-Related Diseases

Liver-related diseases, such as hepatocellular carcinoma (HCC) and cirrhosis, are globally prevalent and significantly contribute to mortality rates. Despite the availability of various imaging techniques for liver evaluation, a consensus regarding the selection of an accurate and safe method remains elusive. As a non-invasive imaging approach, the effectiveness of contrast-enhanced ultrasound (CEUS) in assisting the diagnosis and treatment of liver-related diseases has been established. Compared to conventional methods, CEUS offers notable advantages, including high safety, convenience, accuracy, and cost-effectiveness. Recent advancements have demonstrated the expanded utility of CEUS in liver-related diseases. In addition to diagnosing focal liver lesions, CEUS is increasingly employed for guiding local treatments, assessing liver transplantation suitability, and planning surgical interventions. However, its application requires caution due to the high technical proficiency demanded of operators, time-sensitive imaging processes, and susceptibility to visual interference. This review summarizes the current applications and recent advancements in CEUS-assisted diagnosis and treatment of liver-related diseases, explores its future potential, and proposes possible improvements. The objective is to enhance the accuracy and versatility of non-invasive liver assessments and provide a reference for the broader and more effective utilization of CEUS in liver disease diagnosis and management.
