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

If done with contrast, ct can also detect vascular issues like aortic dissection and aneurysm . Enlarged lymph nodes are also easier to detect on ct. In general, somethings that are easily seen on ct are difficult or impossible to see on chest x-ray. ...Read moreSee 1 more doctor answer
Both use x-rays: A chest ct is a very detailed look at the lung, blood vessels, heart and bony thorax. It takes very thin (3-5mm) slices which allows for detailed analysis of lung structure. The chest x-ray takes a 3-d structure and collapses it to 2-d. This still provides very detailed information of the chest, but can lead to overlap -- sometimes requiring additional views or a ct scan to clear things up. ...Read moreSee 1 more doctor answer

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
