This way the body is shown in slices, in any plane, usually axially, but ...Read more

2 See Ur Intestine: A ct of the abdomen can be very helpful for diagnosing recurrent hernias. An important part of the study is to look at the intestine relative to the hernia. Contrast in the intestine makes the interpretation of these films much easier. ...Read more

I had roux en y novemger 06. I recently had a CT with contrast that showed I had a dilated segment of bowel with an air fluid level. Why?

A ? to ask surgeon: To answer this question, we'd need more details as to why you had to have the ct done. Was there something that was bothersome enough to have it ordered. Did the ct scan show anything else? There is a good chance the surgery didn't go right or something happened in the postoperative period. Your surgeon might be able to address these concerns better since he was the one who did it. ...Read more

CT interpretation: Are u sure you have not had any other contrast imaging study within a few days before this CT you mentioned? If not then the CT you had must have been with contrast.

Bowel issues 3 years, 4 Ct scans over that time with oral contrast, sigmoidoscopy to 35 cm, only diverticulosis seen, chances of missed cancer?

Bowel issues 3 years, 4 Ct scans over that time with oral contrast, sigmoidoscopy to 35 cm, only diverticulosis seen, chances of missed cancer?

Slim: In spite of the low chance of missing a cancer, a complete colonoscopy would examine the rest of the colon not visualized on sigmoidoscopy. CT is only fair to see colon cancers unless large because stool may get in the way. If you are still concerned then talking to your doctor may resolve these issues. ...Read more

Does CT colongraphy see all organs of the abdomen also in result it said upper viscera were unremarkable what does that mean in terms of what they see?

Does CT colongraphy see all organs of the abdomen also in result it said upper viscera were unremarkable what does that mean in terms of what they see?

Almost: The CT colonoscopy should cover the entire abdomen. However, to limit radiation and depending on where your colon is seen, the scan may be shortened. Usually it covers everything. Contrast injections are needed to help identify hidden lesions in the blood vessels, liver and kidney which is not used in CTC. So, in toto, everything is seen from the liver to the urinary bladder but not well. ...Read more

Why might I need a CT of the abdomen with contrast instead of without?

Why might I need a CT of the abdomen with contrast instead of without?

Other Way Around: The best cts are done with contrast: IV dye for eval. Of blood vessels & blood flow; oral dye to better see the intestines.

Can there be such thing as a contrast only abdomen/pelvic ct?

What are different types of hernia in abdomen? Would a CT with oral contrast of abdomen/pelvic show a hernia? Any kind.

Physical Exam Best: The most common hernias of the abdominal wall include the groin/inguinal region, the umbilicus, and the upper-middle abdomen. Hernias may also develop anywhere one has had an incision from prior surgery. The best way to demonstrate a hernia is by physical examination. If unclear, a ct may be helpful but it can miss hernias and, in the groin especially, may not differentiate a hernia from fat. ...Read more

Intestine (Definition)

The gastrointestinal tract starts at the mouth, travel down the tunnel (esophagus), which connects to the stomach, which then empties into the duodenum, jejunum, and ileum---the three parts of the small intestine (@25 feet). This empties into the colon or large intestine (about 5 feet), which then becomes the sigmoid colon, rectum and out the anus. So, every morsel eaten ...Read more
