X-Rays are a form of electromagnetic radiation, which
are primarily used for diagnostic radiography. Digital
x-ray has certain advantages over conventional film
x-ray, including the ability for the x-ray technologist
to immediately tell if the image is acceptable.
X-rays are especially useful in the detection of pathology
of the skeletal system, and also useful for detecting
some disease processes in soft tissue. Some examples
are common chest X-ray, which can be used to identify
lung diseases such as:
pneumonia
lung cancer
pulmonary edema
X-Ray services
include:
Bone densitometry
Bone-X-ray
Chest X-ray
Joint X-ray
Myelography
Discography
IVP (Intravenous Pyelogram)

How do I prepare for my X-Ray?
No preparation is required for general X-ray exams.
However, please tell the staff if you suspect that you
could be pregnant. If you are scheduled for an IVP contact
your Doctor's office for further prep instructions.
Barium Swallow
This is an Fluoroscopy also known as screening examination
using barium (an x-ray detectable liquid) to assist
in the diagnosis of inflammation, ulcers, strictures
or pouches, hernias, tumours and polyps in the upper
digestive tract.
What is Barium?
Barium is a chalky liquid which is used by radiologists
to outline parts of the digestive tract on x-rays. It
is x-ray detectable and makes the x-ray image of the
digestive tract much clearer to see and is an aid to
diagnosing your problem. The patient is given the barium
either to drink which will show the oesophagus ( the
tube your food travels down into the stomach) the stomach
and the small intestine or it can be given rectally
as an enema to outline the large bowel.
You will have been sent for a barium meal because you
have been suffering with symptoms such as:
Difficulty with swallowing
Blood in your vomit
Stomach bloating
Stomach pains
Preparation:
If you are just having a barium swallow to look at
your oesophagus (the tube your food goes down) you will
not be able to eat or drink for only a few hours before
the procedure.
If you are having a barium meal and or follow through
you will be asked not to eat or drink anything after
midnight before your procedure.
Risks:
The risks of the procedure is radiation exposure however
the radiation dose you receive will be the same as you
would naturally be exposed to over a three year period.
The Procedure:
Will be done in the X-ray department and will normally
be done as an outpatient procedure. If you believe you
may be pregnant you should inform the staff prior to
the commencement of the investigation. When you arrive
in the department you will be shown to a cubical and
asked to remove your clothing and put a gown on.
You will be taken through to the X-ray room where you
will be given the barium to drink it is a thick liquid
which usually has a fruit flavour to enhance it.
You will be asked to drink two or three mouthfuls and
then positioned in front of the x-ray machine to see
how the barium is progressing.
You will be given some granules to eat which fizz up
inside your stomach causing gas -try not to burp at
this point as the air is enhancing the x-ray images.
You will be moved about and repositioned on the x-ray
table and asked to hold your breath whilst a series
of x-rays are taken.
The procedure will only take about 10-15 minutes for
a barium swallow. Although you may be in the department
longer while waiting for x-rays to be developed .If
you are having a barium meal and follow through you
will be in the department for up to three hours as x-rays
will need to be taken at regular intervals as the barium
travels through the digestive tract.
The procedure does not cause any pain although you
may feel bloated due to the gas generated in your stomach.
You will be advised to eat a high fibre diet and drink
plenty of fluids over the next few days as the barium
is known to cause constipation.
Barium Meal
Barium is a chalky liquid which is used by radiologists
to outline parts of the digestive tract on x-rays. It
is x-ray detectable and makes the x-ray image of the
digestive tract much clearer to see and is an aid to
diagnosing your problem. The patient is given the barium
either to drink which will show the oesophagus ( the
tube your food travels down into the stomach) the stomach
and the small intestine or it can be given rectally
as an enema to outline the large bowel.
You will have been sent for a barium enema because
you may have been suffering from changed bowel habits
i.e.
Low stomach pains
Bloating feelings
Alternating diarrhoea and constipation
Blood in your bowel movements
Unexplained weight loss
The Preparation:
For the bowels involves eating only a light diet, fluids
and taking laxatives which the staff will give you.
You will be provided with written instructions of what
you can eat and drink and when to take the laxatives.
If you are a diabetic please ensure you ask the staff
for any special instructions. The laxative is very strong
and it is recommended to stay close to a toilet. The
preparation for the procedure is very important if the
bowels are not clear the procedure will not be done
and will have to be rescheduled.
Risks:
The risks of the procedure are few; the bowel may perforate
and the barium might leak into the abdominal cavity,
this happens extremely rarely. The radiation dose you
receive will be the same as you would naturally be exposed
to over a three year period. You may be given a drug
to relax the bowels during the procedure; if you suffer
from heart disease or glaucoma you should inform the
staff of this.
The Procedure:
Will be done in the X-ray department and will normally
be done as an outpatient procedure. If you believe you
may be pregnant you should inform the staff prior to
the commencement of the investigation. When you arrive
in the department you will be shown to a cubical and
shown the location of the nearest available toilet,
you will then be asked to remove all your clothing and
put on a gown, all metal objects, watches and jewellery
should be removed.
You will be made comfortable lying on the X-ray table
with a blanket over you
You will be asked to turn onto your side; a soft rectal
tube will be passed a small way into your rectum.
The barium liquid will then be introduced slowly the
radiologist will then ask you to change positions on
the table to coat the inside of the bowel with the liquid.
Air may also be introduced into the bowel via the
same rectal tube this gives the radiologist a clearer
picture of the bowel.
This procedure is more uncomfortable than painful;
you may experience stomach cramps, and fullness.
You may be given an injection to relax the muscles
of the bowel wall, this may cause blurring of your vision,
but it will pass.
You will have X-rays taken of you in various positions
The procedure can take approximately 20 minutes although
you could be in the department for longer, waiting for
x-rays and visiting the toilet.
When the procedure is over you will be able to go to
the toilet. Some but not all of the barium will be passed.
Your stools when eliminated will be white as this is
the colour of the barium, your stools will continue
to be slightly pale for the next few bowel movements.
The remainder of the barium will naturally be excreted
in your bowel movements; however it can cause constipation
so it is advised that you drink plenty of fluids and
eat a high fibre diet for the next few days.
barium enema
What is a barium enema?
A barium enema, also called a lower gastrointestinal
(GI) series, uses x-rays to diagnose problems in the
large intestine, which includes the colon and rectum.
The barium enema may show problems like abnormal growths,
ulcers, polyps, diverticuli, and colon cancer.
What happens during a barium enema?
Before taking x-rays of your colon and rectum, the
radiologist will put a thick liquid called barium into
your colon via an enema. The barium coats the lining
of the colon and rectum and makes these organs, and
any signs of disease in them, show up more clearly on
x-rays. It also helps the radiologist see the size and
shape of the colon and rectum.
You may be uncomfortable during the barium enema. The
barium will cause fullness and pressure in your abdomen
and will make you feel the urge to have a bowel movement.
However, that rarely happens because the tube used to
inject the barium has a balloon on the end of it that
prevents the liquid from coming back out.
You may be asked to change positions while x-rays are
taken. Different positions give different views of the
colon. After the radiologist is finished taking x-rays,
you will be able to go to the bathroom. The radiologist
may also take an x-ray of the empty colon afterwards.
A barium enema takes about one to two hours. The barium
may cause constipation and make your stool turn gray
or white for a few days after the procedure.
How do you prepare for a barium enema?
Your colon must be empty for a barium enema to be accurate.
To prepare, you will have to restrict your diet for
a few days beforehand. For example, you might be able
to drink only liquids and eat only non-sugar, non-dairy
foods for two days before the procedure; only clear
liquids the day before; and nothing after midnight the
night before.
To make sure your colon is empty, you will be given
a laxative or an enema before the procedure. Your physician
may give you other special instructions.
