Computed Tomography (CT)

Medical imaging using X-rays.

CT spines

CT scans of the spine can provide more detailed information about the vertebrae (bones of the spine) and other spinal structures and tissues than standard X-rays of the spine, thus providing more information related to injuries and/or diseases of the spine.

a CT scan of the spine may be performed to assess the spine for a herniated disk, tumors and other lesions, the extent of injuries, structural anomalies such as spina bifida (a type of congenital defect of the spine), blood vessel malformations, or other conditions.

 

  1. Trauma or Injury: After a traumatic event such as a car accident or fall, a CT scan of the spine can be performed to assess for fractures, dislocations, or other injuries to the vertebral column.

  2. Back Pain: In cases of severe or persistent back pain, especially when associated with suspected spinal issues, a CT scan can help identify the cause, such as herniated discs, spinal stenosis, or degenerative changes.

  3. Evaluation of Disc Herniation: CT scans can provide detailed images of the spinal discs, helping to identify herniated or bulging discs that may be compressing nerves and causing symptoms.

  4. Spinal Stenosis: To assess for narrowing of the spinal canal (spinal stenosis), which can lead to compression of the spinal cord or nerves and cause pain, numbness, or weakness.

  5. Evaluation of Tumors or Masses: A CT scan can help detect and evaluate tumors or masses in or around the spine, including primary spinal tumors or metastatic lesions.

  6. Assessment of Infections: In cases of suspected spinal infections, a CT scan can provide detailed images to assess the extent of infection and guide treatment.

  7. Congenital Abnormalities: CT scans can be used to evaluate congenital abnormalities or malformations of the spine, providing valuable information for diagnosis and treatment planning.

  8. Pre-surgical Planning: Before certain spine surgeries, a CT scan may be performed to help surgeons plan the procedure by providing detailed images of the spine’s anatomy.

  9. Assessment of Degenerative Changes: CT scans can reveal degenerative changes in the spine, such as osteoarthritis, bone spurs, and facet joint disease.

  • You should wear comfortable, loose-fitting clothing to your exam.
  • Metal objects, including jewelry, eyeglasses, dentures and hairpins should be left at home or removed prior to your exam. You may also be asked to remove hearing aids and removable dental work. Women will be asked to remove bras containing metal underwire. You may be asked to remove any piercings, if possible.
  • You should inform the technologist if you have a pacemaker.
  • You may be asked not to eat or drink anything for a few hours beforehand, especially if a contrast material will be used in your exam.
  • You should inform your physician of all medications you are taking and if you have any allergies.
  • Inform your doctor of any recent illnesses or other medical conditions and whether you have a history of heart disease, asthma, diabetes, and kidney disease or thyroid problems.
  • Women should always inform their physician and the CT technologist if there is any possibility that they may be pregnant.
  • Your diet will be restricted to clear liquids the day before the examination
  • Be sure to inform your physician if you have heart, liver or kidney disease to be certain that the bowel prep will be safe.
