Computed tomography is also known as CT scan. 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
Not Designed for it: Not what a ct scan is designed to do. Usually colon cancer will not be clearly evident on ct until it is at stage iii or stage IV level, since it has to anatomically change the colon to be evident on ct. To get that level of change, it needs to be at minimum a locally advanced tumor. Every once in a while it may be evident at the stage ii point, but very low sensitivity. ...Read moreSee 1 more doctor answer

In colon cancer patients, ct is used to look at whether there is measureable disease outside the colon in the lymph nodes and/or liver. ...Read more
Sometimes: Ct colography is never meant to replace a colonoscopy. At high volumn centers, the detection sensitivity of ct exam is indeed comparable to colonoscopy but you need to know the rate of detection of your imaging facility. Bowel prep is required for both procedures - no way around the unpleasant process. Beware that there is significant radiation exposure with the exam. ...Read moreSee 2 more doctor answers

Ct scan showed spot on liver, have colon cancer but ultrasound came back negative does it mean it was wrong?
Pet or MRI may help: Other imaging modalities may help further clarify if this finding in ct is suspicious for malignancy or more likely benign if the ct and ultrasound have not been more specific. If u have older ct scans to compare and this is indeed new, then further clarification is needed. This all has to be taken into context of the bigger clinical picture including cea as well as the rest of your body. ...Read moreSee 2 more doctor answers
Ct scan uses data from a beam of xrays and reconstructs a cross sectional image of your body. It is a high dose of xrays and used only when the benefits outweigh the risk. Cancer risk is 1 in 500 in children. Also using iodinated contrast might cause transient renal failure in about 5% of patients. (contrast induced nepropathy) most do not explain this to the patient as ...Read more
