The focuses of liver ultrasonography and enhanced CT are different, so they need to complement each other for diagnosis. Liver ultrasonography can detect the hemodynamic changes of liver tumors and identify the nature of liver tumors, while CT examination of the liver is mainly an imaging examination, which can analyze and determine the size, number, and location of tumors, and also identify the presence of hemangiomas or cysts, and determine whether there is any metastasis of malignant tumors in the liver. The focus of liver ultrasonography and liver enhancement CT is different, especially when the patient is suspected of having a liver malignancy, a comprehensive assessment can be made based on the results of the two examinations, and liver ultrasonography can be used to assess and evaluate the efficacy of interventional therapy in the case of liver malignancy. When liver malignancy is detected or suspected, it is recommended to consult the Department of Hepatobiliary Surgery of a regular hospital.
