What Is The Difference Between A Barium Enema And A Ct Scan
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 moreGet help from a doctor now ›
Computed tomography is also known as CT scan. 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
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 moreGet help from a doctor now ›
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 moreGet help from a doctor now ›
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 moreGet help from a doctor now ›
very different: During a proctogram, your doctor inserts a tube through the anus into the rectum and looks through the tube. A barium enema is done by inserting a tube in a similar fashion but then filling the colon with barium and watching under x ray to look at the outline of the colon. ...Read moreGet help from a doctor now ›
Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
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
