Extended data:
The accuracy of brain CT in showing the size and location of cerebral infarction focus is 66.5% ~ 89.2%, and the accuracy of showing the first cerebral hemorrhage is 100%. Therefore, early CT examination is helpful for differential diagnosis and can rule out cerebral hemorrhage. When the onset of cerebral infarction is within 24 hours, or the infarction focus is less than 8 mm, or the lesions are in the brain stem and cerebellum, brain CT examination often cannot provide a correct diagnosis. If necessary, it should be reexamined in a short time to avoid delaying treatment.
