What are the color ultrasound findings of liver metastases?
Under normal circumstances, the color ultrasound findings of liver metastases may include reduced liver volume, multiple metastatic foci, unclear boundaries, abnormal blood flow signals, and invasion of the hepatic and portal veins. The details are as follows:
1. Reduced Liver Volume
Color ultrasound examination can clearly assess the severity of liver metastases. During the examination, a明显 reduction in liver size may be observed, primarily due to damage to hepatocytes caused by the disease, leading to liver atrophy.
2. Multiple Metastatic Foci
Liver metastases are usually multiple, with several metastatic lesions present within the liver. These lesions may appear on color ultrasound images as nodules of varying sizes and shapes.
3. Unclear Boundaries
The margins of liver metastases on color ultrasound are typically indistinct, with poorly defined borders between the tumor and surrounding normal liver tissue.
4. Abnormal Blood Flow Signals
Color ultrasound may reveal abnormally increased blood flow signals within the metastatic tumors, appearing as unusual colored flow signals, which helps differentiate metastatic lesions from normal liver tissue.
5. Invasion of Hepatic and Portal Veins
If the liver metastases are large in size, they may invade both the hepatic and portal veins. This can lead to obvious thickening and deformation of the vessel walls, along with significant changes in hemodynamics.
If patients experience any discomfort or symptoms, it is recommended to seek timely medical evaluation at a hospital to avoid delays in diagnosis and treatment.
