NCT02291718

Brief Summary

The purpose of this study is to compare the contrast agents and imaging techniques used for thoracoabdominal aortic imaging in CT. Imaging parameters and contrast volume are changed and adjusted based on the contrast agent, since contrast agents have varying iodine concentrations. If the contrast iodine concentration is higher, it may be possible to adjust the imaging parameters and lower the overall radiation dose to the patient.
