what does an mri scan of the head show
For an MRI of the head, you lie with your head inside a special machine (scanner) that has a strong magnet. The MRI can show tissue damage or disease, such as infection or inflammation, or a tumor, stroke, or seizure. Information from an MRI can be saved and stored on a computer for more study.
A CT scan can reveal tumors, abnormal tissue, and problems with arteries. A scan of the head can provide important information about the brain, for instance, if there is any bleeding, swelling of the arteries, or a tumor.
