What is the difference between a barium enema and a CT colonoscopy?

What is the difference between a barium enema and a CT colonoscopy?

A barium enema has: Slightly more radiation exposure, requires you to flip and turn on the table until the radiologist is satisfied with the images, and in the end reveals slightly less information than the CT. The CT requires slightly less radiation exposure, allows you to lie flat on your back, and gives the radiologist more internal information. But a traditional colonoscopy is the first choice. ...Read more

Computed Tomography (Definition)

Ct uses xrays taken an 360 degrees combined with a computer to see"inside" the body. The table moves as the xray tube and detectors spin around the patient 10 times a second or more! The image shows excellent soft tissue detail, enhanced with injection of intravenous contrast or oral contrast. This way the body is shown in slices, in any plane, usually axially, but ...Read more

What is the difference between a CT colonoscopy and a barium enema?

What is the difference between a CT colonoscopy and a barium enema?

CT colonoscopy: Is a CT scan with specific technical parameters. There is a bowel prep to clear out the colon, and a tube is placed into the rectum to fill the colon with air. A barium enema uses x-ray/fluoroscopy instead of CT. With a rectal tube, the colon is filled with barium and air, and the patient placed in different positions for viewing. Barium enema has been largely replaced by colonoscopy. ...Read more

Is there a difference between a barium swallow and a barium enema?

Is there a difference between a barium swallow and a barium enema?

Location, location: Barium swallow is what it sounds like: swallow barium, shows up on xray film; looks at esophagus, stomach, upper small bowel (duodenum) if done as upper GI series. No prep, empty stomach.
Barium enema looks at the colon (not so good for the rectum). After prep to clean colon, barium (with or without air for contrast) pumped into colon to get an outline on xray. ...Read more

What is difference between colonoscopy and barium enema in terms of information?

Significant: Colonoscopy is a direct look at the lining of the colon vs an indirect x-ray shadow of a barium enema (be). If something is seen on a colonoscopy, it can be treated or biopsied. The be can miss things in the rectum and should include a flex sig to evaluate that area. You are sedated for a colonoscopy. No sedation for a be. Both are acceptable measures for colon cancer screening. ...Read more

What is the difference bewteen a proctogram and barium enema?

In Jan, I had 5 x-rays, c scan and barium enema now I am going to have a non walking nuclear stress test. Is this too radistion in this time. Frame?

The theoretical: Lifetime cancer risk for diagnostic imaging is generally minimal. It is cumulative, but it doesn't really matter whether you had those tests in one day or 6 months apart. So, the answer to your question is no, it won't make a difference within that time frame. ...Read more

Can one get injured during a barium enema test?

Yes, rarely: Rare cases of rectal perforation with the enema tip are known to occur. If there is a weakness of the colon wall from a prior surgical repair there may be leakage of the barium outside of the colon. If we know of such risks we will often start the procedure with water soluble contrast which is less trublesome for leakage but less adequate for imaging. ...Read more

I am having a barium enema done and they told me to use a water enema. I have saline. Is this ok to use?

I am having a barium enema done and they told me to use a water enema. I have saline. Is this ok to use?

Saline is good...: Not too many people stock saline at home, but if you have it at home, it is ok to use with your enema. Saline is basically water +salt+chloride in concentration slightly higher than your plasma (blood fluid without the red/white cells). It is probably a safer enema to use then water, but the difference is likely not significant. Good luck with your procedure. ...Read more

Barium enema after a perirectal abscess surgery, what do you recommend?

Enema is needed: Barium is probably not the contrast media I would choose. I would perform. I would choose a water soluble media. Just in case the cause of the abscess was a hole in the bowel. Better to have water soluble contrast rather than barium. As always best to talk to the doctors ...Read more

Have chronic PID but at the moment treated by doctors words, went for barium enema due to pain in colon. They found nothing. What can be the cause?

Treatment for PID: PID is a condition where a pathogen (sexually transmitted) goes up the cervix and uterus and through the fallopian tubes, into the pelvix, causing a more widespread infection. This is separate from your colon and if you're in severe pain, you will need antibiotic treatment, possibly a laparoscopic surgery if imaging shows an abscess. A barium enema would not be helpful for PID. ...Read more

Barium (Definition)

Barium is a chemical element with symbol ba and atomic number 56. It is the fifth element in group 2, a soft silvery metallic alkaline earth metal. Because of its high chemical reactivity barium is never found in nature as a free element. Its hydroxide was known in pre-modern history as baryta; this substance does not occur as a mineral, but can be prepared ...Read more
