Echo on ultrasound after radiofrequency ablation of the liver may be caused by chronic hepatitis, fatty liver, liver space-occupying lesions and other reasons. 1. Chronic hepatitis: chronic hepatitis can cause liver damage, and ultrasound examination after liver radiofrequency ablation may show diffuse echo enhancement of liver substance. 2. Fatty liver: excessive accumulation of fat in the liver cells will cause fatty liver, ultrasound after liver radiofrequency ablation surgery with echogenicity, usually there will be a thickening of small echoes. 3. Hepatic space-occupying lesions: if there are space-occupying lesions in the liver, such as mass or pericardium, the color ultrasound after radiofrequency ablation of the liver is mostly strong echoes, and the posterior will be accompanied by acoustic shadows. Echo after radiofrequency ablation of the liver ultrasound need to go to the hospital for further examination and consult a specialist for guidance.
