Iodine contrast agent, which is employed in computed tomography (CT), has side effect. If carbon dioxide can be employed as a side effect free contrast agent, CT can be used in annual health check. As a result, early detection of cancer will be more probable. In this study, contrast increase with the usage of carbon dioxide is confirmed by calculation.
