A recent CT scan with contrast revealed two cysts on pancreas. What does this mean? Previous colon cancer and has esld. Also 6mm mass on liver.

A recent CT scan with contrast revealed two cysts on pancreas. What does this mean? Previous colon cancer and has esld. Also 6mm mass on liver.

Needs attention: Needs work up. Most of the pancreatic tumors are solid but cysadenoma, cystadeno carcinoma will present as cystic lesions need biopsy of these lesions to make sure they are not malignant also liver lesion. If pancreatic lesions are benign could be a candidate for liver transplantation for end stage liver disease (esld). ...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

Can CT scan clearly pin point the location of colon perforation and determine the size of the hole, using color contrast drink?

Can CT scan clearly pin point the location of colon perforation and determine the size of the hole, using color contrast drink?

Sometimes: If the perforation is large enough, and the oral contrast is in that loop of bowel, then yes.

A very small hole may not be seen that way, but the ct will show air that has leaked out of the bowel, which can help the surgeons if an open repair is required. ...Read more

Chance of developing colon cancer 20 months after colonoscopy removal 5mm polyp removed. Having ct scan with and without contrast for left quad pain?

Chance of developing colon cancer 20 months after colonoscopy removal 5mm polyp removed. Having ct scan with and without contrast for left quad pain?

See below: If the colonoscopy was done properly, you are very unlikely to have colon cancer 20 months after the procedure.
For good health - Have a diet rich in fresh vegetables, fruits, whole grains, milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Drink enough water daily, so that your urine is mostly colorless. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco, alcohol, weed or street drugs in any form.
Practice safe sex. ...Read more

Can a CT scan of the abdomen/pelvis without contrast detect colon cancer and ulcers?

CT Scan Findings: Ct scan is not the best study to detect colon cancer or ulcers. Although a ct scan may show a large sized colon cancer, the sensitivity of this is greatly reduced without the administration of oral contrast. Ulcers are typically not seen on ct scan. The best diagnostic study for both of these would be an endoscopy and colonoscopy. ...Read more

What does ct scan results mean? Large amount of colonic stool confirm moderate amount of free peritoneal air as well as air in the anterior wall and the retro peritoneum. The study was with IV contrast only.

What does ct scan results mean? Large amount of colonic stool confirm moderate amount of free peritoneal air as well as air in the anterior wall and the retro peritoneum. The study was with IV contrast only.

Prob not good.: The large amount of stool in the colon is not necessarily abnormal BUT, air in the abdomen means the bowel has had a leakage OR it is post surgery.
cannot say in your particular case, but generally, if there isn't surgery, a burst bowel is often fatal. ...Read more

What does incomplete distension of colon mean? Had a CT scan and that was included in results. What is incomplete distension of colon?

Nothing serious: It merely means that your large intestine was partially collapsed on the images, so the radiologist could not see all parts of them. It is not a sign of any sort of dangerous illness. Hope this helps! ...Read more

I had a CT scan done about two weeks ago and I got a copy of the results. It read that I had air-fluid in my small bowels and colon. What is that?

Gas & fluid: It is usually normal to see some air and fluid in the bowels. It also depends on why you had the study done in first place. There are conditions where this becomes important so discuss the results with your doctor ...Read more

I had a CT scan to look for thickening of the wall of my colon. Scan showed no thickening but a contracted gallbladder after fasting. What's the tx?

Unless you have: Symptoms suggesting gallbladder disease I would do nothing. The gallbladder can contract by just drinking some water so a contracted one alone is of doubtful significance. Ultrasound can be used to look for gallstones should there be some need for further evaluation and hepatobiliary scans can look for abnormal gallbladder filling and emptying in patients with suspected gallbladder dysfunction. ...Read more

Ct scan of abdomen shows nothing besides colon, right?

Ct scan of abdomen shows nothing besides colon, right?

Wrong: Ct scanning of the abdomen and pelvis shows the colon, yes, but not subtle mucosal lesions such as early cancer.
It shows your internal organs such as the liver, spleen, kidneys and pancreas in great detail.
It also shows your small intestinal and the numerous blood vessels. It can evaluate the connective tissue and fat to uncover inflammatory conditions or infections. ...Read more

Please tell me, could a CT scan show the pancreas & the colon?

CT will show both: Yes, a ct scan will show both organs, the pancreas and the colon. Contrast material, such as oral or IV contrast may enhance the evaluation. Ct is probably the best modality for pancreatic imaging. For the colon: inflamatory conditions, diverticulosis, and large tumors will usually be easily seen with ct. Small lesions such as polyps within the lumen are better seen with colonoscopy. ...Read more

My CT scan showed that my decending and sigmoid colon was collapsed what does that mean?

ColonDidntFallInADay: Did they use that word? Or did they say "redundant"??
That's just a slightly longer colon that flops around or settles lower than normal and usually keeps out of trouble, except maybe for occasional constipation or cramps. Rarely, it will twist and cause a problem. As long as you are otherwise healthy, hydrated and eating fibre, you should do OK unless, of course it has collapsed, then you're SOL ...Read more

I recently had a CT scan and it came back that I have scattered diverticula. And a collapsed tranverse colon with no blockage. How. Worried should I b?

Two problems: The diverticuli are common and called diverticulosis. It is a problem if they get inflamed or if they rupture.

The collapsed transverse colon depends on the reason for the collapse. It can be a normal or a problem. You need to discuss with your physicians and your gastroentrologist. ...Read more

Why can't a CT scan see colon cancer well? How large would it need to be to be seen?

Not Designed for it: Not what a ct scan is designed to do.

Usually colon cancer will not be clearly evident on ct until it is at stage iii or stage IV level, since it has to anatomically change the colon to be evident on ct. To get that level of change, it needs to be at minimum a locally advanced tumor.

Every once in a while it may be evident at the stage ii point, but very low sensitivity. ...Read more

Does a CT scan detects colon cancer? Or colonoscopy should be done?

? Early detection tes: CT scan is not a good Test for early detection of Colon Cancer, so Colonoscopy is the preferred test because it accomplishes 2 objectives...detect polyps/precursors of colon cancer and remove them at the same time which eliminates the risk of Polyps changing into cancer. If you have difficulty with having Colonoscopy, then you should ask your doctor to suggest some alternative tests for checking. ...Read more

Can a liquid barium drink for CT scan prep irritate the colon after a recent case of diverticulitis?

Can a liquid barium drink for CT scan prep irritate the colon after a recent case of diverticulitis?

Barium is a laxative: What do you mean by "irritation"? Abdominal pain? Increased output? Blood? Barium, for all its use in imaging, is also a laxative & often used as an enema. It will force the stool out of the intestines & colon as it makes its way out. Therefore, "irritation" of the colon (depending on how you define it) isn't uncommon after a barium-contrast CT. It shouldn't cause bleeding nor pain, however. TTYD ...Read more

Can I be screened for colon cancer with a CT scan instead of a colonoscopy?

Sometimes: Ct colography is never meant to replace a colonoscopy. At high volumn centers, the detection sensitivity of ct exam is indeed comparable to colonoscopy but you need to know the rate of detection of your imaging facility. Bowel prep is required for both procedures - no way around the unpleasant process. Beware that there is significant radiation exposure with the exam. ...Read more

A CT scan found that I have moderate diverticulosis in the sigmoid colon. What does this mean?

A CT scan found that I have moderate diverticulosis in the sigmoid colon. What does this mean?

Diverticulosis: Diverticulosis is essentially caused by pressure. Straining at stool causes pressure within the colon, and that pressure seeks to escape through weak points in the intestinal wall. When escaping, the pressure takes some of the intestinal lining along for the ride causing pouches (diverticuli). Low fiber diet leads to straining at stool, hence the recommendation of high fiber diet. ...Read more

I had a CT scan with result: diffuse bowel wall thickening in the rectosigmoid colon. Is this serious?

You need a diagnosis: Diffuse bowel wall thickening in the rectosigmoid can be caused by diverticulosis, which is benign. It can be caused by inflammation (colitis) or ischemia, which is more serious. It can also be caused by cancer. You need to have this followed up to obtain a diagnosis. ...Read more
