Patients who see a gastroenterologist for abdominal pain will often have testing and imaging (most commonly an ultrasound or a CT scan) completed to rule out other causes of abdominal pain.

Can colon polyps be seen on CT scan?

A traditional colonoscopy is the most widely known colorectal cancer screening procedure, but many patients are choosing a non-invasive CT (computerized tomography) Colonography instead. A CT Colonography doesn't require sedation and is just as accurate at detecting most precancerous polyps.

Can CT scan Miss colon?

Conclusion: Colon cancer is undetected in 20% of abdominal CT examinations in patients subsequently proven to have colon cancer at colonoscopy. The absence of fat stranding, vascular engorgement, or lymphadenopathy, and an average tumour length of 3.3 cm are contributing factors for failure of detection.

What are symptoms of small intestine problems?

A CT scan will identify inflamed diverticula, bowel wall inflammation, pericolic fat stranding, and corresponding complications [9,10,11,83,87,88].

How can you tell the difference between small bowel and large bowel on CT?

The small bowel, located centrally within the abdomen, has valvulae conniventes (plicae circulares) which are thin mucosal folds traversing the entire lumen. The more peripheral large bowel has thick haustral folds which, unlike valvulae conniventes, extend partially across the lumen.

A multi-slice CT, which involves a 10 mm collimation, has 98% accuracy in diagnosing acute diverticulitis. This also allows for sensitivity and specificity to be 97% and 98%, respectively. Clinicians are also able to reliably diagnose the complications of acute diverticulitis using CT imaging ( Fig.
