Computed Tomography (CT)

  • About

    Computed tomography, also known as a CT or CAT scan, is a quick, non-invasive diagnostic test that uses x-rays to produce multiple cross-sectional images of the inside of the body and head. The individual images, or “slices”, are recombined to provide a multidimensional view of the body’s interior. CT images show greater detail than traditional x-rays, making them particularly useful in detecting and diagnosing problems in internal organs, soft tissue, and blood vessels. For some CT scans, a contrast material or “dye” may be used to enhance the part of the body being examined; it is typically swallowed by the patient or injected into an IV.

    CT is often used in emergency situations to assess the extent of damage to the head and body, and to help find the cause of non traumatic head and body pain.. It is also one of the best procedures for detecting vascular disease, like blood clots and aneurysms, and some forms of cancer, and is often used to aid needle biopsies and tumor treatments. In addition, CT can help identify and treat problems with the spine, the extremities, and other delicate musculoskeletal structures.

  • Preparation

    Prior to the day of the procedure, you should notify your physician of all your medications and allergies. If you have a known allergy to the contrast material, or “dye”, you may be prescribed a medication to reduce the risk of an allergic reaction. Also inform your physician of any recent illnesses, chronic medical conditions, and whether there is a chance you may be pregnant.

    Do not eat or drink anything for a few hours before your procedure, with the exception of medications.

    Wear comfortable clothing on the day of your exam. Metal objects can affect CT images, so you may be asked to remove piercings and other jewelry, eyeglasses, dentures, hearing aids, and clothing that contains metal, such as pants with zippers or bras with metal underwire. If necessary, a gown will be provided to you for the procedure.
