Comparison of High Iodine Concentration Contrast Material (Isovue 370) vs Standard Protocol (Isovue 300) in Thoracoabdominal Aortic Computed Tomographic Angiography (CTA) for Radiation Dose Reduction
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.
