About this study

The purposes for this study are to determine the ability of volumetric dynamic 4D CTA compared to replace current single-phase CTA and eliminate venous contamination that can decrease scan accuracy. Additionally, we seek to estimate the ability of this new imaging technique (volumetric dynamic 4D CTA) to reduce the dose of intravenous iodine and radiation dose. 

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
