Would advanced colon cancer show up on a CT scan of my abdomen? Reg CT scan not virtual colonoscopy.

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 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

Is a CT scan dangerous to a 23 year old, (abdominal) virtual colonoscopy? How many standard x-rays equivelant roughly?

Is a CT scan dangerous to a 23 year old, (abdominal) virtual colonoscopy? How many standard x-rays equivelant roughly?

Does have some risks: Ct scans do expose you to a modest dose of radiation which is not harmful if you have good indications for doing this test and there is no better alternative. Virtual colonoscopy is not yet proven to replace standard colonoscopy. Moreover it is recommended only for over 50 years of age. Since you are 23 year old, you have to have a good reason to have virtual colonoscopy instead of regular exams. ...Read more

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 more

Clear ab CT scan w/ IV & oral contrast, clear colonoscopy then u/s diagnosis liver hemangioma. Urq pain & tender spot n lower right rear rib. Ideas & nxt step?

See HPB surgeon: The symptoms you describe could well be related to the hepatic hemangioma. The decision to remove will depend on: 1) size (usually remove when > 10 cm); 2) symptomatic (pain, ache, fullness); 3) causing blood problems (when the hemangioma destroys blood cells); 4) causes congestive heart failure. See a surgeon who specializes in liver surgery, a hepatobiliary surgeon. ...Read more

Right ab pain extends 2 back & ribs at times. Intermittent but daily for weeks. Clear CT scan & colonoscopy. Slightly elevated liver enzymes.?

Ultrasound: If you are having pain in the right upper abdomen that goes to the back and elevated liver enzymes, the best test to have is an ultrasound to evaluate for gallbladder disease. Colonoscopy will not see it and ct will miss many. Good luck. ...Read more

Not sure: If you are describing a muscle tremor, it shouldn't be directly related to surgery. Give it some time, it may be spasm in the muscle after the local trauma of surgery. ...Read more

Had a colonoscopy, Dr wants me to get CT scan. Iam not sure why. He removed two polups, I have no pain and bowel movements seem somewhat normal.

Looking for tumor: CAT scan especially of abdomen is used to look for a tumor growth outside of the intestine and possibly evidence of colon tumor spread to the liver. This would only be suggested if the polyps removed were malignant with evidence of tumor invasion to the base of the polyp suggesting invasion of the adjacent mucosa to the polyp ...Read more

A good doctor can he: Hep will come from a good doctor. If the pain is getting worse you need to go back to the doctor, they may need to repeat your x-rays. Scans. If the x-rays are normal, it could be irritable bowel syndrome. But only a gastroenterologist can help you arrive at the right diagnosis. ...Read more

Doc says ibs. I have had mre small bowel, CT scan with vein contrast, colonoscopy, blood tests. All were normal. What are the chances I have crohns?

Very low: If all the above were normal including colonoscopy and colon biopsies then your chances of having crohn's is very slim. New evidence points to fructose and high fructose corn syrup as the culprit in ibs. Try to avoid the for few weeks and see. ...Read more

Male, 61, with IBS (negative virtual colonoscopy 3 years ago).Recent normal abdominal-pelvic MRI, except minimal fluid in recto-vesical pouch. CAT SCAN?!

What for?: MRI usually provides a better image than CAT scan and there is no radiation involved. From what you described, it is not likely that CAT scan would add any value to the imagining studies already done.
Wish you 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, if you have sex. ...Read more

Does a pet CT scan replace a colonoscopy?

Does a pet CT scan replace a colonoscopy?

NO!: Pet/ct is an excellent tool for cancer diagnosis and evaluation of therapy, but it does not actually 'look' at the lining of the colon. Often we see activity in the bowel that has been secreted, so it could mask or mimic a tumor. ...Read more

If I have been diagnosed with diverticulitis by CT scan do I need a colonoscopy?

If I have been diagnosed with diverticulitis by CT scan do I need a colonoscopy?

Possibly: It depends some on your age and past history. Diverticulitis, an infection of the colon, can sometimes show a lot of thickening on ct scan. That can be hard to tell if the infection caused the swelling, or if a tumor is causing the thickening. It is common to recommend a colonoscopy several weeks after the diverticulitis had healed, if you have not already had one. ...Read more

I am suffering from constipation from last 5 years. I hv been done CT scan, barium test, colonoscopy and all reports are fine.

Adjust diet: If your tests so far are negative that is a good sign. Consider following your diet closely and ensuring that you are eating a high fiber diet with plenty of fruits and vegetables as well as ensuring that you are adequately hydrated. I would also suggest looking at gut motility and this can be assessed by a gastrointestinal specialist. Medications can also have an impact. ...Read more

Prominent Spleen was found during a Colonoscopy exam, CT scan (2 weeks later) showed the Spleen was normal - is any further investigation required?

Probably not: The spleen is not actually "seen" directly on colonoscopy. If the CT scan showed a normal size spleen and your doctor has no other reason to suspect an abnormal spleen, then no further tests should be necessary. ...Read more

Had Abd/Pelv CT Scan in Sept'13.Had Abd/PelvMRI in Nov'13.Had Colonoscopy Oct'13.Had numerous hem/anal checks. Doc says no AnalCancer. Still reason2wry?

Why so worried?: It sounds like you have already undergone an extensive evaluation. Rectal and colon cancer are very rare at your age. Typically, a flexible sigmoidoscopy is sufficient in your age group. Given your young age, and extensive studies, I think your risk is low. Are there other symptoms or lifestyle choices that make you worry about anal disease? ...Read more

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

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

What is method to diagnose intestinal tb if colonoscopy and endoscopy and ct scan normal?

What is method to diagnose intestinal tb if colonoscopy and endoscopy and ct scan normal?

Start with: A skin test. If this is negative then TB is quite unlikely. You may react positive though if you've been vaccinated or been sensitized from previous contact. A blood test like the interferon gamma release, unfortunately suffers from similar problems like the skin test. Usually TB enteritis has some radiographic or endoscopic findings. Otherwise all that's left is to empirically treat you. .. ...Read more

Can IBS cause RLQ pain. I have been having pain on&off for 4 months. Had ct scan didn't show anything wrong. What are IBS symptoms? Do I colonoscopy.?

Colonoscopy: Irritable bowel symptoms typically run the spectrum from constipation to diarrhea, frequently alternating back and forth. Usually there is episodic cramping and spasm, but bleeding and weight loss are unusual. Evaluation by your primary care physician may not find any abnormalities in blood tests, x rays or a ct scan. Proceed to Gastroenterology for colonoscopy. ...Read more

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

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

Mother had colonoscopy- they found a small lesion that they believe is cancer. Doing a CT scan next before the remove it? What does the CT show?

CT scan: The ct scan may show the extent of the tumor. For example the ct scan could reveal if the tumor has invaded through the gut wall and is present in the surrounding fat. It could also show if there are large lymph nodes and weather or not there is spread to the liver. ...Read more
