NCT04837846

Brief Summary

To evaluate intravascular attenuation of the coronary arteries and image quality in an individualized scan and CM injection protocol whereas both scan and injection parameters are tailored to the individual patient in a North American, European and Asian patient population. To evaluate the radiation dose and contrast media dose of this individualized approach for CCTA in an American, European and Chinese patient population. To evaluate the injection parameters required for an average American, European and Chinese patient population.

Outcome Measures

Primary Outcomes (1)

  • Evaluation of Intravascular Attenuation

    To measure the amount of Hounsfield units in different anatomical structures produced by an amount of contrast media. Using Hounsfield units coupled with image quality to determine if a scan of diagnostic value has been attained.

    At time of CCTA scan

Study Arms (1)

Prospective CCTA Arm

Other: Differing Tube Voltage Administration

Interventions

Subjects will undergo CCTA utilizing a scan and contrast media injection protocol that will be tailored to individual body habitus.
