CT Scan (Computed Tomography)


A CT scan uses X-rays and computer technology to create cross-sectional images of the brain. It’s often used after head injuries, strokes, or to detect bleeding or swelling.

• Why it matters: Provides quick, detailed imaging during emergencies.

• In children: Doctors limit CT scans to reduce radiation exposure, often opting for MRI unless urgent.

• Statistic: CT scans are performed in over 5 million pediatric cases annually in the U.S. (Radiological Society of North America, 2024).

• What families should know: The test is painless and takes about 5–10 minutes.
