Infarct foci are foci of ischemia that appear after ischemic necrosis of brain tissue and can often be detected by head CT or MRI.
Infarct foci are caused by cerebral infarction. This disease is caused by atherosclerosis of cerebral arteries, occlusion of cerebral blood vessels, interruption of blood flow, and ischemic and hypoxic necrosis of brain tissue. If the patient has previous atrial fibrillation or heart valve disease, etc., the embolus of the atrium is dislodged, and the embolus enters into the cerebral circulation with the blood flow, and the blockage of the lumen of the blood vessel can lead to ischemic-ischemic necrosis of the brain tissue.
Infarct foci are low-density foci in head CT, low signal in T1 and high signal in T2 in head MRI.
The clinical manifestations of infarct foci in different parts of the body may be different, such as vision loss, hearing loss, dysphagia, hemiparesis, hemiplegia, hemiplegia and so on. Patients should seek medical treatment in time and take treatment under the guidance of doctors.
