What to Expect

Prior to Procedure

Your doctor may do the following:
  • Physical exam and medical history
  • Ask if you are pregnant—this test is not usually done on women who are pregnant
  • Ask about your medical history
  • Discuss your medicines with you, as you may need to
    • change the dosing
    • stop them—this is usually true with blood-thinners
  • Determine if you have any allergies
  • Possibly prescribe a mild sedative to help you relax
Leading up to your procedure:
  • The night before, do not eat solid foods after midnight. You should continue to drink liquids.
  • If your doctor prescribes a sedative:
    • Arrange to have someone drive you home. Also, arrange for someone to help you at home.
    • Take the sedative before the exam as directed by your doctor.


There is usually no anesthesia with this procedure. Your doctor may give you a mild sedative. You may have local anesthetic to reduce the pain of the needle.

Immediately After Procedure

You may be asked to stay in the exam room while the doctor looks at the images. You will be able to go home after about an hour.

How Long Will It Take?

About 30-60 minutes (CT scan will take 30-60 minutes longer)

How Much Will It Hurt?

You will have some pressure or pain when the needle is inserted.

Post-procedure Care

  • If you took a sedative, do not drive, operate machinery, or make important decisions until the sedative wears off.
  • Avoid strenuous exercise (including bending over) for 1-2 days.
  • You may be more comfortable lying on your back for 24 hours after the procedure.
