  • Computed Tomography (CT)

    Computed tomography (CT) is a diagnostic imaging technique in which X-rays are taken from different angles and then processed using a special computer to create cross-sectional images of the head, spine, or other part of the body. CT scans are more detailed than standard X-rays.

    In some cases, a contrast agent may be injected into a vein to make it easier to see internal structures. This procedure is called a CT angiography.

    What is Computed Tomography (CT) used for?

    A computed tomography scan may be used to diagnose or determine the cause of the following problems:

    • Brain tumor
    • Trauma
    • Hemorrhage (bleeding)
    • Vertigo (dizziness)
    • Headaches
    • Fainting
    • Deformities
    • Stroke
    • Buildup of fluid inside the skull (hydrocephalus)
    • Brain infection
    • Hearing loss
    • Vision problems
    • Muscle weakness, numbness, or tingling
    • Speaking difficulties
    • Swallowing difficulties
    • Changes in thinking or behavior
    • Degenerative conditions

    A CT angiogram may be used to diagnose cerebrovascular disorders, such as:

    • Blockages in blood vessels
    • Narrowing of blood vessels
    • Aneurysms
    • Other blood vessel abnormalities

    CT imaging may also be used to guide procedures such as surgeries, radiation therapies, and biopsies.

    Am I a good candidate for Computed Tomography (CT)?

    You may be a good candidate for computed tomography if you are having symptoms of a neurological problem or have been involved in an accident. CT scans do expose you to radiation, more so than standard X-rays, so your doctor may recommend another imaging test if you have had several CT scans over time or if you are pregnant.

    You may not be a good candidate for CT angiography if you have impaired kidney function or have had a previous allergic reaction to a contrast agent.
