Patients with cerebral infarction can have an enhanced CT scan, but if the patient is not considered to be a tumor or encephalitis, it is not necessary to have an enhanced CT. For CT enhancement examination, the main method is to apply contrast agent intravenously to the patient, and at present, the commonly used contrast agents in clinical practice are panfluoperazine or methylpanfluoperazine, and then CT examination is performed after applying contrast agent intravenously to the patient. If the patient has a tumor or encephalitis, which causes the blood-brain barrier to be damaged, it can present a high-signal enhancement response in the lesion area, which can help the lesion appear more clearly and increase the positive rate of tumor or encephalitis diagnosis. If you just want to do enhancement for cerebral infarction, it is not clinically recommended for patients to do it, only to perform MRI.
