While there are differences, most conventional x-ray procedures
have basic similarities.
Patient preparation involves removing any articles of clothing
or jewelry that might interfere with the creation of the x-ray image.
The patient is positioned by the technologist so that the anatomy
of interest is in the proper field of view between the x-ray tube
and receptor. The patient is often instructed to hold their breath
in order to prevent the x-ray image from being blurry due to motion.
Patient preparation beyond this, varies according to the body part
to be imaged. Following are some more common examples:
Barium Swallow/Esophagram:
A barium swallow or Esophagram is an x-ray examination that studies
your esophagus. A dense liquid called Barium is swallowed in order
to outline and visualize this soft tissue structure. As you are
swallowing, the radiologist will view the function of your esophagus
under the fluoroscope. X-ray pictures will be taken. The procedure
takes about 15 minutes.
Upper GI:
An Upper GI is a fluoroscopic examination that studies the stomach
and the first part of the small intestine. The stomach is visualized
by having the patient swallow "crystals" that make gas
in the stomach, and a dense liquid called Barium. By coating the
stomach with these two substances the radiologist is able to see
the stomach and how it functions. Images are then taken to capture
the necessary information. This procedure takes about 30 minutes.
Small Bowel Follow Through:
A small bowel follow through is an examination of the small intestine
or small bowel. The patient is required to drink a dense liquid
called Barium. The barium lines the small bowel, and allows this
soft tissue organ to be visualized because of it's density. A series
of timed exposures is taken to monitor the barium as it passes through
the small intestine. The length of time required for this procedure
varies greatly because it relies on the metabolism of the patient
to move the barium through the small intestine. The average time
range for this is exam is from 1 to 6 hours.
Barium Enema:
A "Barium Enema" or Lower GI or Colon x-ray, is a fluoroscopic
examination that studies the large intestines or large bowel. To
prepare for this exam, laxatives are given to cleanse the bowel
prior to the exam. To perform the exam, a dense liquid called Barium
is placed in your bowel through a tube that is inserted into your
rectum. This is followed by air, which is used to distend the bowel.
By turning you in different directions as these substances are inserted,
all surfaces of the colon are coated with the barium and all surfaces
of the colon are visualized. Images are taken as the exam progresses
in order to gain the information needed. This procedure takes approximately
45 minutes.
The Results
Your diagnostic results will be provided to your primary care physician within 12-24 hours. These results may be provided digitally on CD along with viewing software.
