The CT is normal in the majority of persons with epilepsy . Brain abnormalities
that might be detected are atrophy , scar tissue , abnormal blood vessels or
spinal fluid circulation , or tumors . MRI is extremely helpful for identifying brain scar tissue , small brain tumors , and changes in the brain’s white matter . SPECT shows images of how much blood flows through different parts of the brain . PET shows images of how much glucose or oxygen is metabolized by various areas of the brain . Whereas CT and MRI show the brain’s structure , or how it looks , SPECT and PET show its function , or how it works . These procedures are not routinely used in patients with epilepsy. |
