What is x-ray imaging and how does it work?
X-ray imaging uses x-ray waves, a form
of energy that can pass through the body. These energy waves are
used to create an image on a computer screen. They are used to look
at conditions in nearly every part of the body.
Because x-rays pass through different types of body
tissues at different rates, they can be used to create detailed
images of different types of tissues. For example, bones show up
as white images on the film, air-filled tissues are shown as dark
areas, and fat, cartilage, blood, and muscle produce show up as
various shades of grey.
Your doctor may order an x-ray for many reasons.
A few types of x-ray exams are:
- Bone x-rays - can show broken bones
- Chest x-rays - show the heart and lungs
- Lower GI Series - looks at the colon and intestines.
A barium enema is used as a contrast agent
- Upper GI Series - shows the throat and stomach.
Barium is taken orally as a contrast agent
- Spine x-rays - show the backbones and central
nervous system
- Musculoskeletal x-rays - show problems in bones
and muscles
X-rays are a form of ionizing radiation, which means
they create ions which could damage cells. Fortunately, today's
x-ray machines only use small amounts of radiation because they
use computers that help define the image. Studies have shown that
the benefits of x-ray greatly outweigh the risks of radiation exposure,
even when you have many x-ray exams. Even so, we make sure that
we limit your radiation exposure by giving you a lead apron to wear
that protects the sensitive organs of the reproductive system, and
by avoiding x-rays on pregnant women.
What is it like to have an x-ray?
You'll be asked to stand, sit, or lie
near a movable x-ray generator and a digital recording plate. The
technologist will help position you so the doctor will have the
best view of the body. They may give you a lead apron to wear and
will position the machine. Then they will go to a booth to begin
the test. You'll need to stay still and hold your breath for the
moment that the x-ray photograph is being taken (the technologist
will let you know what to do). Usually at least two different images
are taken.
The exam can take anywhere from a few minutes to
an hour, depending on the reason you are having the test done. Afterwards,
you can dress and return to your normal routine. The radiologist,
a doctor, will examine the x-rays and share this information with
your doctor.
In some cases, a substance called a contrast agent
is used to help see areas that normally couldn't be easily seen
on an x-ray. The contrast agent is usually made with barium or iodine
It mat be given orally, intravenously, or via enema. While x-rays
are painless, there can be discomfort associated with contrast agents.
Some patients find taking a contrast agent orally or by enema unpleasant.
After a procedure involving contrast agents, patients may need to
use laxatives and drink extra fluids.
Tell your doctor if you are allergic to barium,
iodine, or shellfish before having an x-ray that involves a contrast
agent.
How should I prepare?
You will not have to do anything special
for most x-ray exams, but if you are having an exam using a contrast
agent, you may need to change the way you eat the day before or
the day of the test. Your doctor can tell you if you need to change
the way you eat, drink, or take your medicines to prepare.
You'll be asked to undress the part of your body
to be examined when you arrive, and you may not want to wear jewelry
and other metal objects.
What
is a Barium Enema and how do I prepare?
A
barium enema (also known as a colon study) involves filling
the colon with barium sulfate and water mixture.
This procedure
lets us see these organs clearly on an x-ray. At least two (2) days
before your procedure you will need to visit the Radiology department
and pick up a bowel prep kit. This bowel prep kit will guide you
on the special diet you will need to follow starting the day before
the exam. This prep is done to ensure the radiologist has a clear
view of your large bowel without the interference of fecal matter
or gas. If you think you might be pregnant, please tell your
provider.
How do I make an appointment?
You, or your doctor's office, can make an appointment
by calling our central scheduling office:
