How much a CT exam costs for a patient with a cerebral infarction depends on the hospital where it is performed. If you visit a level II hospital, a CT scan of the skull is about$200. If you visit a tertiary care hospital, a CT scan of the skull is$250-300, and if you have an enhanced CT scan, it is about$1,000. Cranial CT is one of the most routine examinations for cerebral infarction. Early examination can help patients with cerebral infarction to undergo thrombolytic therapy, and for patients with cerebral infarction, cranial CT is visualized after 24 hours. Some patients may also have characteristic changes within 6 hours of the onset of the disease, such as the disappearance of the cerebral sulcus, or unclear demarcation of the gray and white matter in the area of the nucleus pulposus. For patients with cerebral infarction, CT examination is mainly suitable for the examination of lesions in the cerebral hemispheres as well as in the basal ganglia region, because cerebellar and brainstem infarction, cranial cerebral nuclear magnetic examination has obvious advantages.
