Abstract:
Contrast-enhanced ultrasound（CEUS），as a non-invasive imaging technique，has been widely applied in the characterization of focal liver lesions（FLLs）. By intravenously injecting contrast agents and using specific low mechanical index imaging techniques，CEUS not only provides high spatial and temporal resolution，but also enables dynamic assessment of blood flow perfusion in both large vessels and microvessels，including capillaries in the liver. However，CEUS is highly operator-dependent. The quantitative analysis of time-intensity curves in dynamic contrast-enhanced ultrasound（DCE-US）can provide further information，overcome the subjectivity limitations of traditional CEUS and improve the accuracy of diagnosis and treatment in FLLs. This review discusses the theoretical basis of DCE-US and its quantitative analysis methods，their applications in the diagnosis and treatment of FLLs，limitations，and future directions.
