Cerebral hypoperfusion cannot be detected directly on CT plain scan, but can be determined indirectly. Cerebral hypoperfusion can only be visualized with a CT angiogram.
In CT scanning of the brain, different sections of the brain from the top of the skull to the base of the skull can be viewed, and if the cerebral blood supply is insufficient, ischemic foci, cerebral hemorrhage, and cavernous infarcts or large infarcts in the deep white matter of the brain can be seen.
If cerebral blood supply insufficiency is suspected to be caused by vascular diseases, such as carotid artery stenosis, CT angiography can be used to check the degree and extent of blood vessel stenosis through the three-dimensional reconstruction technology of CT images, so as to find out the causes of cerebral blood supply insufficiency.
It is recommended that patients consult their doctors in a timely manner, and choose the appropriate examination method under the guidance of a professional doctor.
