Computed Tomography Arteriograms (CTA) Volume Dose Reduction Study

Summary

The purpose of the study is to determine if the dose of contrast (Omnipaque) administered for Computed Tomography Arteriograms (CTA) can be reduced without degradation of image quality. The hypothesis is that there is no difference in image quality using ultra-low dose contrast in CTA exams compared to routine, standard of care dose exams.
