NCT06348875

Brief Summary

The primary objective of this study is to determine whether a reduced radiation protocol (RRP) in which angiograms are acquired at ultralow radiation doses and then processed using spatiotemporal enhancement software can produce similar quality angiographic images as compared with standard techniques.

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Patients suspected to have coronary artery disease (CAD) who are undergoing diagnostic coronary angiography with or without possible percutaneous coronary intervention (PCI).

You may qualify if:

  • Referred for clinically indicated coronary angiography
  • ≥18 years of age
  • Not pregnant
  • English speaking
  • Not imprisoned
  • Able to provide written informed consent

You may not qualify if:

  • Hemodynamically or electrically unstable.
  • Indication for coronary angiography is emergent, including ST-segment elevation myocardial infarction
  • History of coronary artery bypass grafting
  • An eGFR \<60
  • Pregnant or lactating
  • A BMI of 45 or greater
  • Any other factor that the investigator feels would put the patient at increased risk or otherwise make the patient unsuitable for participation in the protocol
