Liver ultrasound seems to have a small nodular sensation, suggesting the possible presence of liver nodules. Liver nodules can be seen in liver hemangioma, liver cysts, liver cirrhosis, liver malignant tumors, etc. Usually, it is necessary to combine with liver enhancement ct, tumor markers, liver puncture, liver hardness test and other comprehensive analysis. For example, hepatic hemangioma can be clarified by liver intensified ct; for example, hepatic cyst can be clarified by liver ultrasound; cirrhosis needs to be clarified by combining intensified ct and viral series, liver hardness test, etc.; for example, hepatic malignant tumors can be clarified by combining intensified ct, liver puncture, and tumor markers. Due to the different diseases, the treatment measures are different and the prognosis is different. Like liver cirrhosis, liver malignant tumor will greatly affect the quality of survival and survival period, while liver cysts, liver hemangioma can be cured. For liver ultrasound seems to have small nodules, it is recommended to consult the doctor for further clarification in combination with other tests.
