BRAIN IMAGING: COMPUTED TOMOGRAPHY
SCANS, CORONAL AND SAGITTAL
A and B, Computed tomography (CT) is an x-ray–based imaging approach that is used to view the brain, particularly when looking for differences in tissue density such as the presence of blood. The use of spiral (helical) scanners can quickly provide access to views of slices through the brain at a desired thickness. CT delineates soft tissue, fluid, and bone and can be used with contrast to image blood vessels or to reveal the presence of a tumor caused by a disrupted blood-brain barrier, which allows leakage of the contrast agent into the surrounding extracellular space of the brain.
