How to find cerebral infarction

Clinical symptoms and related examinations Cerebral infarction, also known as ischemic stroke, usually refers to ischemic necrosis or softening of brain tissue caused by blood supply disorder to the brain. The diagnosis of cerebral infarction mainly depends on clinical symptoms and imaging examinations. Patients with cerebral infarction generally show sudden fainting, unconsciousness, hemiplegia, speech disorders, mental retardation and other clinical manifestations. Patients with the above symptoms need to go to the hospital for relevant examinations. First, CT examination is needed. CT examination can rule out cerebral hemorrhage and has very high value in distinguishing cerebral infarction from cerebral hemorrhage. Second, MRI examination is very sensitive to the detection of cerebral infarction. This examination is superior to CT examination and generally can show obvious manifestations in the early stage of ischemia. Magnetic resonance angiography (MRI) and whole brain angiography (CTA) can be performed to determine whether there is stenosis or obstruction of blood vessels.
