Chest CT Using Low-concentration Iodine Contrast Media
Sponsor: Jung Im Jung
Summary
This study aims to evaluate the quality of images when low-concentration iodine contrast agents is used in chest CT with low tube voltage and if they can be used in routine imaging. The primary endpoint of the study was the quality of the image and comparison of chest CT by using low and conventional concentration iodine contrast agents with low tube voltage and chest CT by using the conventional concentration iodine contrast agents with the conventional tube voltage; The secondary endpoint is optimizing chest CT protocol using an iodine contrast agent.
