Hello,
With the question “What contrast agent is used for dual contrast esophagography? ", the doctor answered as follows:
Double contrast esophagography: Technically, you will be used a barium contrast agent (if this is a good drug, it must have adhesion when taken in. The mucosa is high, produces gas to inflate the esophageal tube, but currently there are not many countries with this good drug, usually available in some big centers in the US, Europe, Japan...).
When taking this medicine, you must be performed by a doctor and specialist technician with very meticulous instructions and instructions, need to coordinate and perform smoothly, the image quality obtained will be good. efficiency can be accurately assessed. The doctor will look under the magnifying screen and record the image in time, on time.
This technique usually takes about 45 minutes. After that, the doctor will evaluate and give the results, the time to return the results varies from place to place. Currently, in Vietnam, there are only a few centers that have this type of contrast agent, many places perform this technique with a contrast agent that does not have the above properties (poor mucosal adhesion and injection technique - slightly bad) so the image quality is not really as expected, leading to low diagnostic support.
Besides the strong development of gastrointestinal endoscopy, endoscopic ultrasound, computed tomography.... with new, modern equipment and mature endoscopic techniques, many doctors With more experience, there have been many advances in diagnostics, which have gradually replaced and reduced the need for this technique.
If you still have questions about the use of dual contrast esophagography, you can go to a medical facility of Vinmec Health System for early examination and treatment. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
