Fluoroscopy/Barium Examinations

This radiological procedure is basic for the evaluation of your digestive system. Our team of radiologists performs this procedure with the assistance of one of our technologists.

Fluoroscopy uses a source of radiation (X-Rays) directed toward the patient, but in these examinations, the internal organs must be dyed in order to study them with a radiopaque material (barium). This will absorb more radiation and provide an image in single or double contrast (air may also be added) to study and analyze the structures better.

There is a dynamic aspect to all these studies, which is not found in general radiology. Therefore, the radiologist is often present during these procedures, because the final diagnosis will be both in terms of static images obtained and the dynamic component observed during the examination.

The examination technique chosen will differ, depending on the organ of the digestive system to be investigated. For examinations of the esophagus, stomach and small intestine, you will drink a barium mixture. Afterwards, the technologist and the radiologist will give you instructions for the various positions to be assumed in order to obtain the required images.

On the days following such exams, you must drink plenty of water to effectively get rid of all the liquid that the technologist made you drink and thus prevent possible constipation. Note that your stool will be whitish in the days following this examination, until the barium is completely expelled from the digestive system.

Radiology of the digestive tract allows the use of barium to observe the digestive system. This allows the radiologist to investigate the causes of stomach pain or blood in the stool.


Pregnancy is a contraindication for all examinations that require the ingestion of barium.
*The results of your examination are sent to your referring physician in the days following its completion.
