Can a CT scan tell the difference between diverticulitis and colon cancer?

Does a CT scan show inflammation?

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

Can you see stomach cancer on a CT scan?

CT scans show the stomach fairly clearly and often can confirm the location of the cancer. CT scans can also show the organs near the stomach, such as the liver, as well as lymph nodes and distant organs where cancer might have spread.

The samples may show cancer cells, proteins or other substances made by the cancer. Blood tests can also give your doctor an idea of how well your organs are functioning and if they’ve been affected by cancer. Examples of blood tests used to diagnose cancer include: Complete blood count (CBC).
