Is a CT scan as effective as a colonoscopy?
‘Virtual colonoscopy’ using CT scans is more effective for investigating patients with possible bowel cancer than an X-ray test, says a new study. The researchers say that this less invasive CT colonography (CTC) should now be considered alongside the ‘gold standard’ of colonoscopy.
Do all tumors show up on CT scans?
CT scans can show a tumor’s shape, size, and location. They can even show the blood vessels that feed the tumor – all in a non-invasive setting. By comparing CT scans done over time, doctors can see how a tumor is responding to treatment or find out if the cancer has come back after treatment.
