Application of CEUS in Early Diagnosis and Radiofrequency Ablation Treatment of Hepatocellular Carcinoma

Due to the limitation of many factors in the implementation of surgical treatment for hepatocellular carcinoma, many non-surgical treatment methods have emerged. Radiofrequency ablation (RFA) has been rapidly developed and widely used in clinic due to its minimally invasive, safety and effective characteristics. With the progress and development of ultrasound instruments and contrast agents, the clinical value of contrast-enhanced ultrasound (CEUS) has been widely recognized. It has become an imaging test system compare to enhanced CT (CECT) and enhanced magnetic resonance (CEMTI). On the basis of routine ultrasonography, CEUS enhanced blood flow signals and real-time observation of tissue and microvascular perfusion information by intravenous injection of contrast agent in order to improve the detection rate of lesions and identify benign and malignant lesions by enhanced imaging. To verify the role of conventional ultrasound and enhanced ultrasound in the early diagnosis and radiofrequency ablation of hepatocellular carcinoma, we compared the results of conventional color Doppler ultrasound and contrast-enhanced ultrasound in the diagnosis and treatment of hepatocellular carcinoma. It is concluded that enhanced ultrasound has higher diagnostic rate and higher cure rate than conventional ultrasound, indicating that enhanced ultrasound plays an increasingly important role in the diagnosis and treatment of hepatocellular carcinoma; on the contrary, it provided a reliable guarantee for the diagnosis and treatment of hepatocellular carcinoma.
