Dynamic Assessment of Vascular Run-Offs using a Multi-phase Protocol and Reduced Contrast Bolus

Overview

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.
