Does a normal CT scan exclude pancreatic cancer?

Not entirely: Ct imaging is useful, but pancreatic cancer can be very difficult to visualize on ct.

My pet scan was highly suspicious for malignancy in rt lung.Now onto Bronchoscope so didn't pet confirm cancer?This cancer isn't curable!

PET scan helps but n: A PET scan can show an abnormality where body cells are overactive. This happens commonly with Cancer and with any Infection or inflammation. So a biopsy is required to make the distinction between Inflammation and Cancer. A bronchoscopy may show the tumor or it may be used to get a biopsy by getting near to the tumor ...Read more

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
