Can CT scan detect cerebral infarction?

There are many diseases in our human body. When we get sick, we usually go to the hospital for timely check-up and early recovery to prevent the disease from being delayed for a longer time and causing irreversible consequences. Generally, we can detect external diseases with the naked eye and some superficial examinations. CT examination requires taking that kind of angiography, which is a method of examining the inside of the body. So, can CT detect cerebral infarction?

Cerebral infarction can be detected by CT scan. Cerebral infarction can be detected through symptoms and examinations. However, if it is a cerebral hemorrhage, it is best to do it within 48 hours, otherwise it will not show up. During the recovery period of cerebral infarction, it is necessary to take peripheral circulation improving agents appropriately to reduce platelet aggregation, lower blood lipids, nourish nerves, promote nerve cell metabolism, pay attention to blood pressure and other treatments. For those with coronary heart disease, rheumatic heart disease, and diabetes, attention should be paid to the treatment of the primary disease.

If CT scan can detect cerebral infarction in the early stage, especially within 24 hours of onset, or the infarction focus is smaller than 8mm, or the infarction site is in the cerebellum or brain stem, then if we check the cranial CT scan, it will often cause some deviations. In a case like this, if we check the brain CT scan, we may not find the lesion, and the brain CT scan may be normal, resulting in missed diagnosis or misdiagnosis. Therefore, we recommend that you repeat the brain CT scan after 48 hours, or preferably an MRI, which can often provide a more definitive diagnosis.

The examinations for cerebral infarction mainly include CT and MRI examinations. Routine electrocardiogram examinations should be performed, etc. 1. CT and MRI examinations can show ischemic infarction or hemorrhagic infarction changes. Combined hemorrhagic infarction highly supports cerebral embolism. Many patients have secondary clinical symptoms of hemorrhagic infarction and aggravate the onset. Repeated CT within 3-5 days of onset can detect bleeding after infarction at an early stage and adjust the treatment plan in time. MRA can detect the degree of carotid artery stenosis or occlusion. 2. Lumbar puncture with normal intracranial pressure and increased intracranial pressure indicates large-area cerebral infarction. Hemorrhagic infarction may show bloody or microscopic red blood cells in the cerebrospinal fluid; infectious cerebral embolism has an increased cell count in the cerebrospinal fluid (mainly granulocytes in the early stage and mainly lymphocytes in the late stage); fat embolism has fat globules in the cerebrospinal fluid. 3. Routine electrocardiogram examinations should be performed to determine the evidence of myocardial infarction, rheumatic heart disease, arrhythmia, etc. Cerebral embolism can be the first symptom of myocardial infarction, which is not uncommon. Carotid artery ultrasound examination can evaluate the degree of lumen stenosis and atherosclerotic plaques, which is suggestive of confirming carotid artery-derived embolism.
