Barium Swallow
A Gastrointestinal Series (G.I.) is an x-ray examination of your esophagus (the passage from the
mouth to the stomach), the stomach and the duodenum (the first part of your intestine).
A Barium Swallow is an x-ray that takes pictures of the passage from the mouth to the stomach
(pharynx and the esophagus).
Preparation
• Preparation begins on the day prior to the exam.
• Patients with diabetes and allergies should consult their Physician for changes in preparation.
Inform the office staff and technologist immediately on arrival.
• You may have a normal supper the evening prior to the examination.
• You are not to eat or drink anything from 8 p.m. on the evening prior to the examination until it
has been completed.
• No medications are to be taken the morning of the examination.
• Do not swallow water when brushing your teeth in the morning.
• Do not wear jewelry to your appointment.
• Children may not be left unattended in the Waiting Room.
• Please let the Technologist know if you have any allergies or if there is any chance of
pregnancy.
Children Under 12
• May eat and drink in the evening.
• Not to eat or drink in the morning.
Newborn - 2 Years
• Nothing to eat or drink 3 hrs. prior to exam time.
• Children with diabetes should fast 2 hrs. prior to the exam.
Procedure
• You will be instructed to change into a hospital gown. You may leave underwear on except an
underwire bra. Remove neck chains and earrings.
• You will be instructed to take some carbon dioxide crystals to produce gas and asked not to
burp. Immediately after this, you will be asked to drink a flavored barium suspension.
• The X-Ray Technologist will ask you to swallow a white chalk-tasting mixture (barium sulphate
and water) several times during the test.
• The Technologist will ask you to move in different positions. The table is motorized and will
also move.
• You may be asked to hold your breath during image capture. Your Technologist will tell you if
delayed pictures are required.
• If a small bowel follow-through is also ordered you will be asked to drink another cup of
barium. This will require images to be taken after extended periods of time to evaluate your
small bowel. Please ensure that you have this time available to complete the exam (up to 6
hours, average 1.5 hours). You may be allowed to leave and return to the department.
After the Test
• The Technologist will tell you when your examination is complete. It is recommended that you
increase your water/clear fluid intake over the next few days as barium can be constipating.
• The barium is excreted through your stools. Your stool will be lighter in colour. Y
• Your Physician may want you to take a laxative if you should become constipated after the
test.

EARLY LIFE
• Wilhelm Conrad Röntgen was born on March 27,
1845, at Lennep in the Lower Rhine Province of
Germany, as the only child of a merchant in, and
manufacturer of, cloth.
• When he was three years old, his family moved to
Apeldoorn in The Netherlands, where he went to the
Institute of Martinus Herman van Doorn, a boarding
school.
• He did not show any special aptitude, but showed a love
of nature and was fond of roaming in the open country
and forests.


EDUCATION
• In 1862 he entered a technical school at Utrecht, where
he was however unfairly expelled, accused of having
produced a caricature of one of the teachers, which was
in fact done by someone else.
• In 1865, he was unfairly expelled from high school when
one of his teachers intercepted a caricature of one of the
teachers, which was drawn by someone else.
• Without a high school diploma, Röntgen could only
attend university in the Netherlands as a visitor. Upon
hearing that he could enter the Federal Polytechnic
Institute in Zurichhe passed the entrance examination
and began studies there as a student of mechanical
engineering. In 1869, he graduated with a PhD from the
University of Zurich.


CAREER
• In 1874, Röntgen became a lecturer at the University of
Strasbourg. In 1875, he became a professor at the
Academy of Agriculture at Hohenheim, Württemberg.
• He returned to Strasbourg as a professor of physics in
1876, and in 1879, he was appointed to the chair of
physics at the University of Giessen.
• In 1888, he obtained the physics chair at the University
of Würzburg, and in 1900 at the University of Munich, by
special request of the Bavarian government. He
remained in Munich for the rest of his career.

 Röntgen’s first work was published in 1870, dealing with
the specific heats of gases, followed a few years later by
a paper on the thermal conductivity of crystals.
• Among other problems he studied were the electrical
and other characteristics of quartz; the influence of
pressure on the refractive indices of various fluids; the
modification of the planes of polarised light by
electromagnetic influences; the variations in the
functions of the temperature and the compressibility of
water.
