How To Prepare
Before the X-ray test, tell your
doctor if you are or might be pregnant. The
risk of radiation exposure to your unborn baby (fetus) must be
considered. The risk of damage from the X-rays is usually very low compared
with the potential benefits of the test. If a spinal X-ray is absolutely
necessary, a lead apron will be placed over your belly to shield your baby
from the X-rays.
You may need to take off any jewelry that may be in the way of the X-ray
picture, such as if you have a pierced belly button.

How It Is Done
A spinal X-ray is taken by a radiology
technologist. The X-ray pictures are usually read by a doctor who specializes
in reading X-rays (radiologist).
You will need to remove any
jewelry that may be in the way of the X-ray picture. You may need to take off
some of your clothes, depending on which area is examined. You will be given a
cloth or paper gown to use during the test. You may be allowed to keep on your
underwear if it does not get in the way of the test.
X-ray test, you will lie on an X-ray table. If the X-ray is being taken because
of a possibly serious injury to your neck or back, to prevent causing more injury a radiologist will look at
the first X-ray pictures before taking others.
If you have a neck brace (cervical collar) in place, X-ray pictures may be
taken and a physical exam done to see whether the brace can be taken off
without hurting the spine.
Usually 3 to 5 X-ray pictures are
taken. You need to lie very still to avoid blurring the pictures.
A spinal X-ray usually takes about 15 minutes. You will wait about 5
minutes until the X-rays are processed in case more pictures need to be
taken. In some clinics and hospitals, X-ray pictures can be shown right away
on a computer screen.
