Computed Axial Tomography (CAT or CT)
Computed Axial Tomography (CAT or CT) scans produce cross-sectional pictures to create 3-D brain images that will show the brain’s density and any abnormalities, such as swelling, bleeds (called hematomas), and skull fractures. Though not as sensitive as MRI scans, CT scans take less time to perform and are typically the first scans taken in the hospital.
