A bad ultrasound after healing of hepatitis C is considered to be an abnormal imaging display of the liver, which may show increased coarsening of the light spots or calcified foci suggestive of a previous infection. Diagnosis of patients with hepatitis C requires a combination of liver elastography, hepatitis C viral replication counts, and hepatitis C antibodies. Liver ultrasound can be performed to clarify hemodynamics, liver size, and morphology, but the presence of liver ultrasound abnormalities alone does not indicate a liver lesion. After patients with hepatitis C have been cured, the number of hepatitis C virus replications has dropped to normal range, and hepatitis C antibody is positive, which indicates that they have been infected with hepatitis C. Ultrasonography may show thickening of liver spots or calcified foci, which can only indicate that they have been infected in the past, and it is not possible to judge that they still have hepatitis C. Therefore, liver ultrasonography can be used to determine the hemodynamics and morphology of the liver. Therefore, for the abnormalities of liver ultrasound, it is necessary to combine with the specific clinical symptoms of the patient to determine, and it is recommended to consult the Department of Infection of regular hospitals.
