X-rays with contrast medium for cancer diagnosis

Intraperitoneal x-ray imaging is an imaging test to evaluate the anatomical structure of the upper gastrointestinal tract. The esophagus, stomach and duodenum (the head of the intestine) will be prominent on the X-ray film thanks to the contrast medium. This contrast medium may be a barium solution or a contrast agent dissolved in water. If only contrast material is used to evaluate the pharynx and esophagus, this process is called barium swallowing.

X-rays use an invisible electric beam to produce tissue images in the internal organs, bones or organs in the film. X-rays that an X-ray technique to reproduce images of organs in the body help the doctor to diagnose the disease. When shooting, X-rays will go through your body and strike a shield behind you from the image.
When should you carry a x-ray of the gastrointestinal tract with contrast?
Intraperitoneal x-ray is performed to:
Find the cause of gastrointestinal symptoms such as difficulty swallowing, vomiting, belching, indigestion;
Find the narrow area of ​​the upper gut, ulcer, tumor, pyloric stenosis;
Locate areas of inflammatory bowel disease, malabsorption syndrome, bowel movement problems to push food away (peristalsis);
Swallow foreign objects.
Usually, you will not have a gastrointestinal x-ray on contrast if you have no gastrointestinal symptoms. You should do this if:
Difficult to swallow food;
Intestinal obstruction;
Abdominal pain that gets better or worse during the meal;
Hot xảy occurs frequently.
Things to be cautious
What should you know before performing an x-ray of the gastrointestinal tract?
In certain cases, endoscopy is performed as a substitute for a contrast-enhanced x-ray examination of the gastrointestinal tract. Endoscopy uses a thin tube to observe the esophagus, stomach and duodenum.
Upper GI scan:
It is not possible to show gastric mucosal irritation (gastritis) or esophagus (esophagitis) or ulcers less than 0.25 in (6 mm) in diameter.
Helicobacter pylori infection (a bacterium that can cause stomach ulcers) can not be detected.
When any abnormalities are detected, a biopsy can not be performed while a positive x-ray examination of the gastrointestinal tract is performed.
Before proceeding with this medical technique, you should understand the warnings and notes. If you have any questions, please consult your physician for more information and specific instructions.
Implementation process
What should you prepare before performing a contrast-enhanced x-ray?
You should change diet for 2 – 3 days before performing the test. You will be asked to switch to a diet low in fiber. Your doctor will also tell you not to eat or smoke after midnight the night before the test.
Before performing an x-ray of the upper gastrointestinal tract, you will need to wear a hospital gown and be instructed to remove all jewelry, including breast, navel, navel, denture, hair clip, or other objects. Other uses may appear on X-rays if not removed.
Ask your health care provider if you need to change the dose of the medication you are taking. Usually, you can continue to take medication as usual. Do not change the dose yourself without telling the health care provider.
You will be asked to remove jewelry on the neck, chest or abdomen before the test.
How does the procedure of imaging x-rays on the digestive tract contrast?
You will perform an X-ray test before taking a barium compound. Then swallow this compound several times during the subsequent X-ray. An imaging physician will tell you when to drink and how much water to drink. Often you may have to drink 1 glass (240 ml) or 2.5 milliliters (600 ml) of barium during the test.
The radiologist looks at the amount of barium flowing down the digestive tract using fluorescents and X-rays. The bed you are lying will be changed and you will also change the position so that the barium flows down the body. Maybe the technician will put pressure on your abdomen with a waist or a technician’s hand. You will probably be asked to cough your doctor for visual diagnosis to observe the flow of barium.
If you use a gas contrast agent, you will sip the barium liquid with a syringe with a gastric gassing agent. Thanks to this amount of gas, doctors can see the lining of the stomach and intestines in more detail.
If you have an examination in the small intestine, the imaging physician will look at the flow of barium through the small intestine to the large intestine. X-ray images are taken in 30 minutes.
The test will take about 30 – 40 minutes. If the test extra intestine, it will last 2 – 6 hours. In some cases, you are asked to come back after 24 hours to get more X-rays.
