If you want to determine whether there are symptoms of infection after an imaging operation, you can make a comprehensive judgment based on specific signs and laboratory tests. If a patient develops symptoms of infection after an imaging procedure, abnormal reactions such as bleeding, abscesses, or pain of varying degrees at the site of the imaging procedure will usually occur. At the same time, the subcutaneous tissues at the operation site may also have localized abscesses or abnormal subcutaneous elevations, which may indicate that the operation site may be infected and require further diagnosis. If there are symptoms of infection at the imaging site, it is recommended to go to the hospital for blood tests and imaging tests. Abnormal increases in white blood cells and neutrophils in routine blood tests and abnormal shadows or density images on imaging can help determine whether infection is present. If there are symptoms of infection after the imaging test, you should go to the hospital for examination.
