Hello,
CT colonography is a medical imaging procedure which uses x-rays and computers to produce two- and three-dimensional images of the colon (large intestine) from the lowest part, the rectum, all the way to the lower end of the small intestine and display them on a screen. It is more convenient for patients who cannot get colonoscopy done. But biopsy cannot be done with this procedure. This is the reason that you have undergone sigmoidoscopy and biopsy.
You should wait for the biopsy report and not get exposed to radiations again and again by getting any further CT/ MRI done.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
I was diagnosed with Crohn's disease in the colon when a CT Colonography
showed nothing it was followed by a sigmoidoscopy and biopsy. What i really want to know is, if i have complications in the small bowel would it show up in the CT Colonography images or do i need to have an MRI of the abdomen ? I'm very anxious
