Colon Cancer On Ct With Oral Contrast
Sometime: Unfortunately the exam you mention only discloses larger tumors. A "Vitrual colonoscopy" is a more sensitive test. It involves a preparation of the bowel . The "gold standard" is, of course a colonoscopy by a Gastroenterologist, you are too young to require this on a "routine basis" Do you have symptoms???? Hope this helps Dr Z ...Read moreSee 2 more doctor answers
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Can ibs, ibd or ulcerative colitis be diagnosed by contrast iv, oral contrast and rectal contrast ct scan?
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 moreSee 1 more doctor answer
Potentially: it could show up on CT if large enough, but small tumors may not be visualized. ...Read more
It can sometimes: Unfortunately, ct scans are not very good at finding small polyps like a colonoscopy does. The scan will usually only pick up larger lesions. The endoscopy has an additional benefit of allowing small polyps to be biopsied or removed. Polyps tend to grow to become cancer, so they should be removed if possible. Ct scan, won't allow treatment at same time, and thus, is not as good a test for colon ca. ...Read moreSee 1 more doctor answer
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
Would advanced colon cancer show up on a CT scan of my abdomen ? Reg CT scan not virtual colonoscopy.
Imaging/biopsy: The imaging modality of ct scan could show findings that would be concerning for cancer, mass around your colon, enlarged lymph nodes in the same area. However, the diagnosis is made at biopsy, a piece of the mass under the microscope of a pathologist. Often the ct scan leads to the biopsy. Good luck, it is important to get the evaluation completed. ...Read moreSee 3 more doctor answers
If MRCP & CT scan with contrast were clear of Pancreatic Cancer, what are chances EUS can find Pancreatic Cancer? Are odds on my side with clear MRCP?
Pancreatic cancer: Was the CT tailored for pancreatic mass protocol? If so it is highly accurate for detecting even very small panc masses. If it was a routine CT, the accuracy is still high, but very small tumors may not be seen. MRCP is also not specifically tailored to look for panc mass, so very small lesions may not be seen. No test is 100%, so it is always possible that another test could pick something up. ...Read moreSee 2 more doctor answers
Can an abdominal CT with oral and IV solutions show colon cancer? What cancers can this test show?
Often: Ct scan is a very good way to detect pancreatic cancer, but there are a few caveats. One, no test is 100% accurate. Two, some cancers may not be detected on ct scan because of the way the study was performed. Three, some may not be detectable due to small size or location. There may need to be other tests such as ERCP or endoscopic ultrasound. ...Read moreSee 2 more doctor answers
Symptoms of colon caner (blood, change in habits, pain) for five years, 5 CT scans (with oral / not iv contrast) clear? Cancer still likely?Scope Feb
Not Ca: Blood and changes in bowel habit may be early signs of colon Ca but if not progressive and when scans and a 5 year interval pass and there is no signs of metastatic tumor then we are dealing with an inflammatory bowel process that should have been identified by colonoscopy and bx. ...Read more
Several things: Can be seen on ct scan. The oral contrast helps deliniate some of the intestinal findings. Other organs are also seen such as liver, pancreas, gallbladder, aorta, lymph nodes, kidneys, urinary bladder, uterus or prostate, vertebral column, etc. Some structures are seen better than others. ...Read moreSee 1 more doctor answer
Diagnosed with a "tortuous colon" via oral barium CT scan & colonoscopy; have very distended abbdomen, pain, etc. What to do?
High fiber diet: The elongated colon may need help from a high fiber diet. Avoiding foods and medications that cause constipation is also important. Ask your doctor if there are other issues that may need to be addressed, as the tortuous colon may not be the explanation for your current complaints. ...Read moreSee 1 more doctor answer
It could: There are many ways to diagnosis cancer. In reference to the ovary the simplest, safest, and easiest test is a pelvic ultrasound. If the ovary is abnormal it can be followed with serial ultrasounds or an MRI could be perfermormed. That would be the best imaging test. That being said ovarian cancers can be diagnosed with ct but usually it's because the ct was done for some other reason. ...Read more
Possible: Usually w/o oral contrast it would be hard to see the inside of the stomach; however, if the tumor is large enough or there has been spread outside of the stomach it may still be possible to see. I believe the best way to know if there is disease within the stomach is to undergo an upper endoscopy where the esophagus, stomach and portion of the duodenum are visualized with a camera. ...Read more
Would a CT scan of the abdominal without contrast detect pancreatic cancer, or any other abdominal cancers?
Not very well: Only very large abdominal tumors can be reliably detected with a non-contrast CT scan. Contrast is a dye that is either injected or swallowed (usually both) to improve the quality of the CT scan. Many tumors are essentially invisible without contrast enhancement. Patients with kidney disease may need to be especially careful before taking the contrast dye, as it can have side effects. ...Read moreSee 1 more doctor answer
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
