Colon Scan Vs
The c.T. Scan results says that my colon has become twisted for a possible "internal hernia". Wha's this means?
Hernia is Internal: A loop of bowel can protrude through a hole (defect) in the mesentery which supports the bowel in the abdomen. Such a protruding loop can become trapped (incarcerated) or become twisted and block its' blood supply and be strangulated. These conditions can then lead to obstruction or/and perforation of the bowel. If actually present, the condition would require surgical repair. ...Read more
Rectal Scan: Is all that is needed. The procedure could be done with banding in an office setting, if needed. ...Read more
No: There is variable uptake throughout the bowel on pet scans due to a number of factors (e.g., bowel motility, types of cells in the bowel or inflammation). It is not uncommon to have areas of focal uptake in the bowel. Stool, per se, should not cause increased uptake, though bowel activity may lead to a focal "hot spot.". ...Read moreSee 2 more doctor answers
Diverticulosis attack treated with antibotics can arrest further devlopment? Colon scan indicates two pouches locatedi n the lower colon near rectum
Diverticulitis?: I'll assume you are asking about the role of antibiotics in diverticulitis. Diverticulosis is the presence of outpouches in the colon wall. It presents with bleeding. Diverticulitis is infection of one of those areas, it will present variably with pain, fever, diarrhea, nausea, inability to defecate, and even sepsis. Diverticulitis is treated with antibiotics, but additional therapy may be needed. ...Read moreSee 1 more doctor answer
Why does my wife need chemo? My wife was operated on for colon cancer it went well they removed 12 lymphnodes 4 of them had traces of cancer we just had a petscan and it came back clean no organs affected.Why would my wife need chemo if scan was clean.?
PET : Pet scans usually can only see tumor measuring about the size of a small raisin (1 cm). A tumor this size already contains about 1 billion cancer cells. When multiple lymph nodes are invovled there is a very high chance that there are tiny clusters of cells in other lymph nodes, surrounding tissues, or organs. Chemotherapy or other treatments are often given after surgery to hopefully kill these remaining bad cells. We know that this increases the chances of beating the disease based on randomized trials in which brave people who had colon cancer in their lymph nodes and normal scans after the operation agreed to get chemotherapy or not based on the flip of a coin. Those who got the chemotherapy lived longer and had relapses less often and later in life. ...Read moreSee 1 more doctor answer
Do u need one?: Not every patient who's had colon cancer (or any other cancer, for that matter) needs routine ct or pet scans. It depends a lot on the stage of the cancer and any other factor that would make your doc concerned about spread. This is a great question that would be best answered by the doc who knows your situation the best. I wish you success. ...Read moreSee 1 more doctor answer
It depends.: It's not the size of a metastatic nodule that matters, but where it is located. If it is located adjacent to the actual tumor, it means something different then it does if it is located in a distant organ, such as the liver or lungs. Your doctor should go over the results of the pet scan in detail with you. Good luck. ...Read more
Can colon cancer spread to a aortocaval node ? This was note few months after surgery by a pet scan .
How many months/ years does it take for mets to be visible with colon cancer ? My dad had all clear scans until after surgery.
6 mo to one year: Many feel that if a lesion is localized, Dukes A that mets wont occur. If a C2 lesion with 4 or more nodes present and preop scans are neg while there is a high incidence of recurrent or metastatic tumor it will take somewhere around one year for cells that have broken free prior to surgery to implant and grow to present with scan visibility. That's why in such cases adjuvanct chemo employed . ...Read more
Is it true that colon cancer can take years before causing symptoms? So a cat scan i had just a month ago showing nothing could be good news?
Yes...: Colon and rectal cancer is usually a slowly growing tumor in the colon or rectum. From its earliest beginnings as a colon polyp its estimated to take 10-15 years to grow into a cancer. A standard ct scan of the abdomen/pelvis is not a good or accurate test for early detection of colon cancer. Colonoscopy is the best test for early detection of polyps or cancer in the rectum and colon. ...Read moreSee 1 more doctor answer
A new findin of a liver lesion with 2.8 SUV uptake on pet scan in a colon can patient . Would this b a killed met?
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 moreSee 1 more doctor answer
If colon cancer was there several years n now removed - why only after surgery a liver met appears ? All prior scans were showing no distant spread ?
Not unusual.: It sometimes takes years for a metastasis in the liver or elsewhere to become large enough to be seen with the tests that we have available, such as CT scans or pet scans. If the metastasis is isolated and small, it may still be able to be treated. Be sure to discuss this in depth with your oncologist. Good luck. ...Read more
Other good tests: Early colon cancer is not easily visible on Ultrasound. CT scan is under trials to find out its utility. Right now the best test is Colonoscopy where it is easy to visuallise early colon cancer and precursor lesions. Ask your doctor in case you may need one done. it is recommended for all adults aged 50 years or earlier if there is a family history of colon cancer. Ask your doctor's advice. ...Read more
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
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
