Computed Tomography (CT) Scan of the Spine
CAT Scan, Spine, CT (Computed Tomography), Spine, Spinal CT
Risks
The chance of a CT scan causing a problem is small.
- There is a chance of an allergic reaction to the dye (contrast material).
- If you have diabetes or take metformin (Glucophage), the dye may cause problems. Your doctor will tell you when to stop taking metformin and when to start taking it again after the test so you will not have problems.
- You may have nausea or vomiting after the test.
- There is a small chance of an infection at the needle site on your spine or bleeding into the space around the spinal cord.
- Intrathecal injections may cause a headache. On rare occasions, seizures may occur after an injection of intrathecal contrast material.
- There is a slight chance of developing cancer from having tests that use radiation. The chance is higher in children or people who have many radiation tests. If you are concerned about this risk, talk to your doctor about the amount of radiation this test may give you or your child and confirm the test is needed.
After the test
Call 911 or other emergency services immediately if you have a seizure.
Call your doctor immediately if you:
- Have pain, weakness, or numbness in your legs.
- Have a severe headache.
- Have a headache that lasts more than 24 hours.
- Feel extremely irritable.
- Have problems urinating or having a bowel movement.
- Develop a fever.
